+##### 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.

+
+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

+            Creative techniques
+            Strategic planning
+            Argument mapping
+```

+
+## Note
+
+- Currently, tidy-tree is primarily supported for mindmap diagrams.

+Mermaid just introduced a Visual Editor for Entity Relationship diagrams, letting anyone map database structures through a simple point-and-click interface instead of code. This no-code ER builder now sits alongside Mermaid’s editors for flowcharts, sequence, and class diagrams, enabling teams to craft and share polished data models for apps, AI, and business processes.

+# @mermaid-js/examples
+
+The `@mermaid-js/examples` package contains a collection of examples used by tools like [mermaid.live](https://mermaid.live) to help users get started with new diagrams.
+
+You can duplicate an existing diagram example file, e.g., `packages/examples/src/examples/flowchart.ts`, and modify it with details specific to your diagram.
+
+Then, 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, which should be marked as the default. It's a good idea to add more examples to showcase different features of the diagram.
+
+## Usage
+
+```bash
+pnpm add @mermaid-js/examples
+```
+
+A sample usage of the package in mermaid.live, to get the default example for every diagram type:
+
+```ts
+import { diagramData } from '@mermaid-js/examples';
+
+type DiagramDefinition = (typeof diagramData)[number];
+
+const isValidDiagram = (diagram: DiagramDefinition): diagram is Required<DiagramDefinition> => {
+  return Boolean(diagram.name && diagram.examples && diagram.examples.length > 0);
+};
+
+export const getSampleDiagrams = () => {
+  const diagrams = diagramData
+    .filter((d) => isValidDiagram(d))
+    .map(({ examples, ...rest }) => ({
+      ...rest,
+      example: examples?.filter(({ isDefault }) => isDefault)[0],
+    }));
+  const examples: Record<string, string> = {};
+  for (const diagram of diagrams) {
+    examples[diagram.name.replace(/ (Diagram|Chart|Graph)/, '')] = diagram.example.code;

+
+This package provides a bidirectional tidy tree layout engine for Mermaid based on the non-layered-tidy-tree-layout algorithm.
+
+> [!NOTE]
+> The Tidy Tree Layout engine will not be available in all providers that support mermaid by default.
+> The websites will have to install the @mermaid-js/layout-tidy-tree package to use the Tidy Tree layout engine.
+
+## Usage
+
+```
+---
+config:
+  layout: tidy-tree
+---
+mindmap
+root((mindmap))
+  A
+  B
+```
+
+### With bundlers
+
+```sh
+npm install @mermaid-js/layout-tidy-tree
+```
+
+```ts
+import mermaid from 'mermaid';
+import tidyTreeLayouts from '@mermaid-js/layout-tidy-tree';

+## Tidy Tree Layout Overview
+
+tidy-tree: The bidirectional tidy tree layout
+
+The bidirectional tidy tree layout algorithm creates two separate trees that grow horizontally in opposite directions from a central root node:
+Left tree: grows horizontally to the left (children alternate: 1st, 3rd, 5th...)
+Right tree: grows horizontally to the right (children alternate: 2nd, 4th, 6th...)
+
+This creates a balanced, symmetric layout that is ideal for mindmaps, organizational charts, and other tree-based diagrams.
+
+Layout Structure:
+[Child 3] ← [Child 1] ← [Root] → [Child 2] → [Child 4]
+↓ ↓ ↓ ↓
+[GrandChild] [GrandChild] [GrandChild] [GrandChild]

+/**
+ * Bidirectional Tidy-Tree Layout Algorithm for Generic Diagrams
+ *
+ * This module provides a layout algorithm implementation using the
+ * non-layered-tidy-tree-layout algorithm for positioning nodes and edges
+ * in tree structures with a bidirectional approach.
+ *
+ * The algorithm creates two separate trees that grow horizontally in opposite
+ * directions from a central root node:
+ * - Left tree: grows horizontally to the left (children alternate: 1st, 3rd, 5th...)
+ * - Right tree: grows horizontally to the right (children alternate: 2nd, 4th, 6th...)
+ *
+ * This creates a balanced, symmetric layout that is ideal for mindmaps,
+ * organizational charts, and other tree-based diagrams.
+ *
+ * The algorithm follows the unified rendering pattern and can be used
+ * by any diagram type that provides compatible LayoutData.
+ */
+
+/**
+ * Render function for the bidirectional tidy-tree layout algorithm
+ *
+ * This function follows the unified rendering pattern used by all layout algorithms.
+ * It takes LayoutData, inserts nodes into DOM, runs the bidirectional tidy-tree layout algorithm,
+ * and renders the positioned elements to the SVG.
+ *
+ * Features:
+ * - Alternates root children between left and right trees
+ * - Left tree grows horizontally to the left (rotated 90° counterclockwise)
+ * - Right tree grows horizontally to the right (rotated 90° clockwise)
+ * - Uses tidy-tree algorithm for optimal spacing within each tree
+ * - Creates symmetric, balanced layouts
+ * - Maintains proper edge connections between all nodes
+ *
+ * Layout Structure:
+ * ```
+ * [Child 3] ← [Child 1] ← [Root] → [Child 2] → [Child 4]
+ *     ↓           ↓                     ↓           ↓
+ * [GrandChild]  [GrandChild]      [GrandChild]  [GrandChild]
+ * ```
+ *
+ * @param layoutData - Layout data containing nodes, edges, and configuration
+ * @param svg - SVG element to render to
+ * @param helpers - Internal helper functions for rendering
+ * @param options - Rendering options
