+# Mermaid Key Components: Code Examples
+
+This document provides concrete code examples demonstrating how Mermaid's key components work together.
+
+## Diagram Type Examples
+
+### Flowchart Diagram Structure
+
+```typescript
+// packages/mermaid/src/diagrams/flowchart/flowDiagram.ts
+export const diagram = {
+  parser: flowParser, // JISON parser for flowchart syntax
+  get db() {
+    // Database for managing diagram state
+    return new FlowDB();
+  },
+  renderer, // SVG renderer function
+  styles: flowStyles, // CSS styles specific to flowcharts
+  init: (cnf: MermaidConfig) => {
+    if (!cnf.flowchart) {
+      cnf.flowchart = {};
+    }
+    // Configuration initialization
+    cnf.flowchart.arrowMarkerAbsolute = cnf.arrowMarkerAbsolute;
+  },
+};
+```
+
+### Sequence Diagram Structure
+
+```typescript
+// packages/mermaid/src/diagrams/sequence/sequenceDiagram.ts
+export const diagram: DiagramDefinition = {
+  parser, // JISON parser for sequence syntax
+  get db() {
+    return new SequenceDB(); // Manages participants, messages, loops
+  },
+  renderer, // Draws actors, lifelines, messages
+  styles, // Sequence-specific styling
+  init: (cnf: MermaidConfig) => {
+    if (!cnf.sequence) {
+      cnf.sequence = {};
+    }
+    if (cnf.wrap) {
+      cnf.sequence.wrap = cnf.wrap;
+    }
+  },
+};
+```
+
+## Core API Examples
+
+### Main API Usage Pattern
+
+```typescript
+// packages/mermaid/src/mermaidAPI.ts
+
+/**
+ * Parse and validate diagram syntax
+ */
+async function parse(text: string, parseOptions?: ParseOptions): Promise<ParseResult> {
+  addDiagrams(); // Load all diagram types
+  const { code, config } = processAndSetConfigs(text);
+  const diagram = await getDiagramFromText(code);
+  return { diagramType: diagram.type, config };
+}
+
+/**
+ * Render diagram to SVG
+ */
+async function render(
+  id: string,
+  text: string,
+  svgContainingElement?: Element
+): Promise<RenderResult> {
+  const { diagramType, config } = await parse(text, { suppressErrors: true });
+
+  // Create diagram instance
+  const diagram = new Diagram(text, {}, diagramType);
+
+  // Render to SVG
+  const svgCode = await diagram.renderer.draw(text, id, diagram);
+
+  return {
+    diagramType,
+    svg: svgCode,
+    bindFunctions: diagram.db.bindFunctions,
+  };
+}
+```
+
+### Diagram Detection Example
+
+```typescript
+// packages/mermaid/src/diagram-api/detectType.ts
+
+export const detectors: Record<string, DiagramDetector> = {
+  flowchart: {
+    detector: (text: string) => /^\s*graph|flowchart/.test(text),
+    loader: async () => {
+      const { diagram } = await import('../diagrams/flowchart/flowDiagram.js');
+      return { id: 'flowchart', diagram };
+    },
+  },
+  sequence: {
+    detector: (text: string) => /^\s*sequenceDiagram/.test(text),
+    loader: async () => {
+      const { diagram } = await import('../diagrams/sequence/sequenceDiagram.js');
+      return { id: 'sequence', diagram };
+    },
+  },
+};
+
+export const detectType = function (text: string, config?: MermaidConfig): string {
+  for (const [diagramType, { detector }] of Object.entries(detectors)) {
+    if (detector(text, config)) {
+      return diagramType;

+## Rendering System Examples
+
+### Layout Algorithm Integration
+
+```typescript
+// packages/mermaid/src/rendering-util/render.ts
+
+interface LayoutAlgorithm {
+  render(
+    layoutData: LayoutData,
+    svg: SVG,
+    helpers: InternalHelpers,
+    options?: RenderOptions
+  ): Promise<void>;
+}
+
+const layoutAlgorithms: Record<string, LayoutLoaderDefinition> = {};
+
+export const registerLayoutLoaders = (loaders: LayoutLoaderDefinition[]) => {
+  for (const loader of loaders) {
+    layoutAlgorithms[loader.name] = loader;
+  }
+};
+
+// Default layout loaders
+const registerDefaultLayoutLoaders = () => {
+  registerLayoutLoaders([
+    {
+      name: 'dagre',
+      loader: async () => await import('./layout-algorithms/dagre/index.js'),
+    },
+    {
+      name: 'elk',
+      loader: async () => await import('./layout-algorithms/elk/index.js'),
+    },
+  ]);
+};
+
+export const render = async (data4Layout: LayoutData, svg: SVG) => {
+  const layoutDefinition = layoutAlgorithms[data4Layout.layoutAlgorithm];
+  const layoutRenderer = await layoutDefinition.loader();
+  return layoutRenderer.render(data4Layout, svg, internalHelpers);
+};
+```
+
+### Unified Renderer Example
+
+```typescript
+// packages/mermaid/src/diagrams/er/erRenderer-unified.ts
+
+export const draw = async function (text: string, id: string, _version: string, diag: any) {
+  const { securityLevel, er: conf, layout } = getConfig();
+
+  // Extract data from parsed structure into Layout data format
+  const data4Layout = diag.db.getData() as LayoutData;
+
+  // Create the root SVG element
+  const svg = getDiagramElement(id, securityLevel);
+
+  // Configure layout
+  data4Layout.type = diag.type;
+  data4Layout.layoutAlgorithm = getRegisteredLayoutAlgorithm(layout);
+  data4Layout.config.flowchart!.nodeSpacing = conf?.nodeSpacing || 140;
+  data4Layout.config.flowchart!.rankSpacing = conf?.rankSpacing || 80;
+  data4Layout.direction = diag.db.getDirection();
+  data4Layout.markers = ['only_one', 'zero_or_one', 'one_or_more', 'zero_or_more'];
+  data4Layout.diagramId = id;
+
+  // Render using layout algorithm
+  await render(data4Layout, svg);
+
+  // Setup viewport
+  setupViewPortForSVG(svg, conf.padding, conf.useMaxWidth);
+};
+```
+
+## Class Diagram Renderer Examples
+
+### Traditional Renderer (v2)
+
+```javascript
+// packages/mermaid/src/diagrams/class/classRenderer.js
+
+export const draw = function (text, id, _version, diagObj) {
+  const conf = getConfig().class;
+
+  // Create directed graph using graphlib
+  const g = new graphlib.Graph({
+    multigraph: true,
+  });
+
+  g.setGraph({
+    isMultiGraph: true,
+  });
+
+  // Add classes as nodes
+  classes.forEach(function (classDef) {
+    const node = svgDraw.drawClass(diagram, classDef, conf, diagObj);
+    idCache[node.id] = node;
+    g.setNode(node.id, node);
+  });
+
+  // Add relationships as edges
+  relations.forEach(function (relation) {
+    g.setEdge(
+      getGraphId(relation.id1),
+      getGraphId(relation.id2),
+      { relation: relation },
+      relation.title || 'DEFAULT'
+    );
+  });
+
+  // Apply layout
+  dagreLayout(g);
+
+  // Position nodes
+  g.nodes().forEach(function (v) {
+    if (v !== undefined && g.node(v) !== undefined) {
+      root
+        .select('#' + (diagObj.db.lookUpDomId(v) || v))
+        .attr(
+          'transform',
+          'translate(' +
+            (g.node(v).x - g.node(v).width / 2) +
+            ',' +
+            (g.node(v).y - g.node(v).height / 2) +
+            ' )'
+        );
+    }
+  });
+
+  // Draw edges
+  g.edges().forEach(function (e) {
+    if (e !== undefined && g.edge(e) !== undefined) {
+      svgDraw.drawEdge(diagram, g.edge(e), g.edge(e).relation, conf, diagObj);
+    }
+  });
+};
+```
+
+### Modern Unified Renderer (v3)
+
+```typescript
+// packages/mermaid/src/diagrams/class/classRenderer-v3-unified.ts
+
+export const draw = async function (text: string, id: string, _version: string, diag: any) {
+  const { securityLevel, state: conf, layout } = getConfig();
+
+  // Extract data from parsed structure into Layout data format
+  const data4Layout = diag.db.getData() as LayoutData;
+
+  // Create the root SVG element
+  const svg = getDiagramElement(id, securityLevel);
+
+  // Configure layout settings
+  data4Layout.type = diag.type;
+  data4Layout.layoutAlgorithm = getRegisteredLayoutAlgorithm(layout);
+  data4Layout.nodeSpacing = conf?.nodeSpacing || 50;
+  data4Layout.rankSpacing = conf?.rankSpacing || 50;
+  data4Layout.markers = ['aggregation', 'extension', 'composition', 'dependency', 'lollipop'];
+  data4Layout.diagramId = id;
+
+  // Use unified rendering system
+  await render(data4Layout, svg);
+
+  // Add title
+  utils.insertTitle(
+    svg,
+    'classDiagramTitleText',
+    conf?.titleTopMargin ?? 25,
+    diag.db.getDiagramTitle()
+  );
+
+  setupViewPortForSVG(svg, padding, conf?.useMaxWidth);
+};
+```
+
+## Configuration System Example
+
+### Type-Safe Configuration
+
+```typescript
+// packages/mermaid/src/config.type.ts
+
+export interface MermaidConfig {
+  theme?: 'default' | 'dark' | 'forest' | 'neutral';
+  themeVariables?: any;
+  startOnLoad?: boolean;
+  securityLevel?: 'strict' | 'loose' | 'antiscript' | 'sandbox';
+  deterministicIds?: boolean;
+  fontSize?: number;
+
+  // Diagram-specific configurations
+  flowchart?: FlowchartDiagramConfig;
+  sequence?: SequenceDiagramConfig;
+  class?: ClassDiagramConfig;
+  state?: StateDiagramConfig;
+  er?: ErDiagramConfig;
+  // ... other diagram configs
+}
+
+export interface FlowchartDiagramConfig extends BaseDiagramConfig {
+  diagramPadding?: number;
+  htmlLabels?: boolean;
+  nodeSpacing?: number;
+  rankSpacing?: number;
+  curve?: CurveStyle;
+  useMaxWidth?: boolean;
+  defaultRenderer?: 'dagre-d3' | 'dagre-wrapper' | 'elk';
+}
+```
+
+### Configuration API
+
+```typescript
+// packages/mermaid/src/config.ts
+
+let config: MermaidConfig = assignWithDepth({}, defaultConfig);
+let directives: MermaidConfig = {};
+let currentConfig: MermaidConfig = assignWithDepth({}, defaultConfig);
+
+export const getConfig = (): MermaidConfig => currentConfig;
+
+export const setConfig = (conf: MermaidConfig): MermaidConfig => {
+  updateCurrentConfig(conf);
+  return getConfig();
+};
+
+export const reset = (): void => {
+  config = assignWithDepth({}, defaultConfig);
+  directives = {};
+  updateCurrentConfig(config);
+};
+
+const updateCurrentConfig = (conf: MermaidConfig): void => {
+  currentConfig = assignWithDepth({}, config, directives, conf);
+};
+```
+
+## Web Integration Example
+
+### Simple Usage
+
+```html
+<!DOCTYPE html>
+<html>
+  <head>
+    <script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>
+  </head>
+  <body>
+    <div class="mermaid">
+      graph TD A[Start] --> B{Decision} B -->|Yes| C[Action 1] B -->|No| D[Action 2]
+    </div>
+
+    <script>
+      mermaid.initialize({
+        startOnLoad: true,
+        theme: 'dark',
+      });
+    </script>
+  </body>
+</html>
+```
+
+### Advanced Programmatic Usage
+
+```javascript
+// Advanced integration example
+import mermaid from 'mermaid';
+
+// Initialize with configuration
+mermaid.initialize({
+  startOnLoad: false,
+  theme: 'default',
+  securityLevel: 'strict',
+  flowchart: {
+    useMaxWidth: true,
+    htmlLabels: true,
+  },
+  sequence: {
+    actorMargin: 50,
+    boxMargin: 10,
+    boxTextMargin: 5,
+    noteMargin: 10,
+    messageMargin: 35,
+  },
+});
+
+// Render specific diagram
+async function renderDiagram(definition, element) {
+  try {
+    const { svg } = await mermaid.render('graphDiv', definition);
+    element.innerHTML = svg;
+  } catch (error) {
+    console.error('Error rendering diagram:', error);
+  }
+}
+
+// Parse and validate before rendering
+async function validateAndRender(definition, element) {
+  try {
+    const parseResult = await mermaid.parse(definition);
+    console.log('Valid diagram type:', parseResult.diagramType);
+
+    const { svg } = await mermaid.render('graphDiv', definition);
+    element.innerHTML = svg;
+  } catch (error) {
+    console.error('Invalid diagram syntax:', error);
+  }
+}
+```
+
+## Extension Example: Custom Diagram Type
+
+### Custom Diagram Definition
+
+```typescript
+// example-diagram/exampleDiagram.ts
+import type { DiagramDefinition } from '../../diagram-api/types.js';
+
+export const diagram: DiagramDefinition = {
+  parser: {
+    parse: (text: string) => {
+      // Custom parsing logic
+    },
+  },
+  get db() {
+    return {
+      clear: () => {},
+      // ... other required DB methods
+    };
+  },
+  renderer: {
+    draw: async (text: string, id: string, version: string) => {
+      // Custom rendering logic
+      const svg = d3.select(`#${id}`);
+      // ... create SVG elements
+    },
+  },
+  styles: () => `
+    .example-class {
+      fill: #ff6b6b;
+      stroke: #333;
+    }
+  `,
+};
+```
+
+### Registration and Usage
+
+```typescript
+// Register custom diagram
+import { registerDiagram } from 'mermaid';
+import { diagram } from './exampleDiagram.js';
+
+registerDiagram('example', diagram, (text) => text.includes('example'));
+
+// Now can use in text:
+const diagramText = `
+example
+  nodeA --> nodeB
+`;
+```
+
+This comprehensive set of examples demonstrates how Mermaid's modular architecture enables powerful diagram generation while maintaining extensibility and type safety.

+# Mermaid: Overview of Main Functionality and Key Components
+
+## What is Mermaid?
+
+Mermaid is a JavaScript-based diagramming and charting tool that uses Markdown-inspired text definitions to create and modify complex diagrams. The main purpose of Mermaid is to help documentation catch up with development by enabling users to create easily modifiable diagrams that can be integrated into production scripts and documentation workflows.
+
+**Core Philosophy**: "Doc-Rot is a Catch-22 that Mermaid helps to solve" - providing a solution to the common problem where diagramming costs precious developer time and gets outdated quickly, but not having diagrams hurts productivity and organizational learning.
+
+## Main Functionality
+
+### 1. **Text-to-Diagram Conversion**
+
+- Converts Markdown-inspired text definitions into SVG diagrams
+- Supports over 15+ different diagram types
+- Real-time rendering and preview capabilities
+- Integration with popular platforms (GitHub, GitLab, etc.)
+
+### 2. **Interactive Diagram Creation**
+
+- Live Editor for interactive diagram creation
+- Web integration module for embedding in web pages
+- Dynamic rendering and modification capabilities
+
+### 3. **Extensible Architecture**
+
+- Plugin system for custom diagram types
+- Configurable themes and styling
+- Multiple layout algorithms support
+- External diagram definition loading
+
+## Key Components
+
+### Core Architecture
+
+#### 1. **Entry Points & API Layer**
+
+- **`mermaid.ts`**: Main web page integration module, provides the primary interface for users
+- **`mermaidAPI.ts`**: Core API containing functions for parsing and rendering diagrams
+- **`Diagram.ts`**: Main diagram abstraction class that handles diagram lifecycle
+
+#### 2. **Configuration System**
+
+- **`config.ts`** & **`config.type.ts`**: Centralized configuration management
+- **`defaultConfig.ts`**: Default configuration values
+- Supports runtime configuration updates and diagram-specific settings
+
+#### 3. **Parser & Detection System**

+
+### Diagram Types (Located in `/src/diagrams/`)
+
+Mermaid supports a comprehensive set of diagram types, each with its own parser, renderer, and styling:
+
+#### **Core Diagram Types:**
+
+1. **Flowchart** - Flow diagrams with nodes, edges, and decision points
+2. **Sequence** - Interaction diagrams between actors over time
+3. **Class** - Object-oriented modeling diagrams
+4. **State** - State machine and statechart diagrams
+5. **Gantt** - Project timeline and scheduling charts
+6. **Git** - Git branching and merging visualizations
+
+#### **Specialized Diagram Types:**
+
+7. **Pie** - Data visualization pie charts
+8. **User Journey** - User experience journey mapping
+9. **C4** - C4 architecture diagrams (Context, Container, Component, Code)
+10. **ER (Entity-Relationship)** - Database modeling diagrams
+11. **Mindmap** - Hierarchical mind mapping
+12. **Architecture** - System architecture diagrams
+13. **Block** - Block diagrams
+14. **Kanban** - Kanban board visualization
+15. **Packet** - Network packet diagrams
+16. **Quadrant** - Four-quadrant analysis charts
+17. **Radar** - Radar/spider charts
+18. **Requirement** - Requirements modeling
+19. **Sankey** - Flow diagrams showing quantities
+20. **Timeline** - Chronological event timelines
+21. **Treemap** - Hierarchical data visualization
+22. **XYChart** - Scatter plots and line charts
+
+#### **Diagram Structure Pattern:**
+
+Each diagram type follows a consistent structure:
+
+```typescript
+export const diagram = {
+  parser: parserDefinition, // JISON or custom parser
+  db: databaseClass, // Data management and state
+  renderer: rendererFunction, // SVG rendering logic
+  styles: stylingDefinition, // CSS styling
+  init: initializationFunction, // Setup and configuration
+};
+```
+
+### Rendering System
+
+#### 1. **Core Rendering (`rendering-util/`)**
+
+- **`render.ts`**: Main rendering orchestrator with pluggable layout algorithms
+- **`createGraph.ts`** & **`createText.ts`**: Basic shape and text creation
+- **`insertElementsForSize.ts`**: Element sizing and positioning
+- **`setupViewPortForSVG.ts`**: SVG viewport management
+
+#### 2. **Layout Algorithms (`layout-algorithms/`)**
+
+- **Dagre**: Default hierarchical layout algorithm
+- **Elk**: Advanced layout engine with multiple algorithms
+- **Cose-Bilkent**: Physics-based layout for complex graphs
+- **Tidy-Tree**: Tree layout algorithm
+
+#### 3. **Styling & Theming**
+
+- **`themes/`**: Multiple built-in themes (default, dark, forest, neutral, etc.)
+- **`styles.ts`**: CSS-in-JS styling system
+- Theme inheritance and customization capabilities
+
+### Security & Safety
+
+#### 1. **Security Levels**
+
+- **Sandbox Mode**: Renders diagrams in sandboxed iframes to prevent script execution
+- **Loose Mode**: Standard rendering with sanitization
+- **Strict Mode**: Enhanced security with limited functionality
+
+#### 2. **Content Sanitization**
+
+- **DOMPurify Integration**: XSS protection for user-generated content
+- Input validation and sanitization
+- Safe handling of external content
+
+### Extension & Integration System
+
+#### 1. **External Diagram Support**
+
+- Dynamic loading of custom diagram types
+- Plugin architecture for extending functionality
+- External diagram definition interface
+
+#### 2. **Layout Extension**
+
+- Pluggable layout algorithms
+- Custom layout loader registration
+- Runtime algorithm selection
+
+#### 3. **Icon System**
+
+- **`icons.ts`**: Icon pack management
+- SVG icon rendering
+- Customizable icon libraries
+
+### Package Structure (Monorepo)
+
+The repository uses a monorepo structure with pnpm workspaces:
+
+#### **Main Packages:**
+
+- **`packages/mermaid/`**: Core Mermaid library
+- **`packages/mermaid-example-diagram/`**: Example external diagram
+- **`packages/mermaid-layout-elk/`**: Elk layout algorithm
+- **`packages/mermaid-layout-tidy-tree/`**: Tidy tree layout
+- **`packages/mermaid-zenuml/`**: ZenUML integration
+- **`packages/parser/`**: Parser utilities
+- **`packages/tiny/`**: Minimal Mermaid build
+
+#### **Supporting Infrastructure:**
+
+- **`docs/`**: Documentation and website content
+- **`demos/`**: Example implementations
+- **`cypress/`**: End-to-end testing
+- **`tests/`**: Unit and integration tests
+
+### Development & Build System
+
+#### 1. **Build Pipeline**
+
+- **ESBuild**: Fast JavaScript bundling
+- **TypeScript**: Type checking and compilation
+- **Vite**: Development server and hot reloading
+
+#### 2. **Testing Strategy**
+
+- **Vitest**: Unit testing framework
+- **Cypress**: End-to-end visual regression testing
+- **Applitools**: Visual testing integration
+- **Argos**: PR visual regression testing
+
+#### 3. **Code Quality**
+
+- **ESLint**: JavaScript/TypeScript linting
+- **Prettier**: Code formatting
+- **Husky**: Git hooks for pre-commit checks
+- **CSpell**: Spell checking for documentation
+
+## Integration Ecosystem
+
+### Official Integrations

+
+## Usage Patterns
+
+### 1. **Direct Web Integration**
+
+```javascript
+import mermaid from 'mermaid';
+mermaid.initialize({ startOnLoad: true });
+```
+
+### 2. **Programmatic API Usage**
+
+```javascript
+const { svg } = await mermaid.render('graphDiv', 'graph TD; A-->B');
+```
+
+### 3. **Configuration & Customization**
+
+```javascript
+mermaid.initialize({
+  theme: 'dark',
+  flowchart: { useMaxWidth: true },
+  sequence: { actorMargin: 50 },
+});
+```
+
+## Future Extensibility
+
+The architecture is designed for extensibility through:
+
+- **Plugin System**: Easy addition of new diagram types
+- **Layout Algorithms**: Pluggable layout engines
+- **Theming**: Comprehensive theme customization
+- **Output Formats**: Support for multiple output formats
+- **Integration APIs**: Well-defined interfaces for third-party integration
+
+This modular architecture makes Mermaid a powerful platform for diagram generation that can grow and adapt to new use cases while maintaining backward compatibility and performance.

+##### Testing the DOM
+
+One can use `jsdomIt` to test any part of Mermaid that interacts with the DOM, as long as it is not related to the layout.
+
+The function `jsdomIt` ([developed in utils.ts](../../tests/util.ts)) overrides `it` from `vitest`, and creates a pseudo-browser environment that works almost like the real deal for the duration of the test. It uses JSDOM to create a DOM, and adds objects `window` and `document` to `global` to mock the browser environment.
+
+> \[!NOTE]
+> The layout cannot work in `jsdomIt` tests because JSDOM has no rendering engine, hence the pseudo-browser environment.
+
+Example :
+
+```typescript
+import { ensureNodeFromSelector, jsdomIt } from './tests/util.js';
+
+jsdomIt('should add element "thing" in the SVG', ({ svg }) => {
+  // Code in this block runs in a pseudo-browser environment
+  addThing(svg); // The svg item is the D3 selection of the SVG node
+  const svgNode = ensureNodeFromSelector('svg'); // Retrieve the DOM node using the DOM API
+  expect(svgNode.querySelector('thing')).not.toBeNull(); // Test the structure of the SVG
+});
+```
+
+They can be used to test any method that interacts with the DOM, including for testing renderers. For renderers, additional integration testing is necessary to test the layout though.
+
 #### Integration / End-to-End (E2E) Tests
 
 These test the rendering and visual appearance of the diagrams.

 The actual options and values for the colors are defined in **src/theme/theme-\[xyz].js**. If you provide the options your diagram needs in the existing theme files then the theming will work smoothly without hiccups.

+## Examples
+
+The `@mermaid-js/examples` package contains a collection of examples that are used by tools like mermaid.live to help users get started with the new diagram.
+
+You can duplicate an existing diagram example file, eg: `packages/examples/src/examples/flowchart.ts`, and modify it with details specific to your diagram.
+
+Then you can import the example in the `packages/examples/src/index.ts` file and add it to the `examples` array.
+
+Each diagram should have at least one example, and that should be marked as default. It is good to add more examples to showcase different features of the diagram.

+
+This page lists the available layout algorithms supported in Mermaid diagrams.
+
+## Supported Layouts
+
+- **elk**: [ELK (Eclipse Layout Kernel)](https://www.eclipse.org/elk/)
+- **tidy-tree**: Tidy tree layout for hierarchical diagrams [Tidy Tree Configuration](/config/tidy-tree)
+- **cose-bilkent**: Cose Bilkent layout for force-directed graphs
+- **dagre**: Dagre layout for layered graphs
+
+## How to Use
+
+You can specify the layout in your diagram's YAML config or initialization options. For example:
+
+```mermaid-example
+---
+config:
+  layout: elk
+---
+graph TD;
+  A-->B;
+  B-->C;
+```
+
+```mermaid

+# Tidy-tree Layout
+
+The **tidy-tree** layout arranges nodes in a hierarchical, tree-like structure. It is especially useful for diagrams where parent-child relationships are important, such as mindmaps.
+
+## Features
+
+- Organizes nodes in a tidy, non-overlapping tree
+- Ideal for mindmaps and hierarchical data
+- Automatically adjusts spacing for readability
+
+## Example Usage
+
+```mermaid-example
+---
+config:
+  layout: tidy-tree
+---
+mindmap
+root((mindmap is a long thing))
+  A
+  B
+  C
+  D
+```
+
+```mermaid
+---
+config:
+  layout: tidy-tree
+---
+mindmap
+root((mindmap is a long thing))
+  A
+  B
+  C
+  D
+```
+
+```mermaid-example
+---
+config:
+  layout: tidy-tree
+---
+mindmap
+root((mindmap))
+    Origins
+      Long history
