   - `on`

-If you want to resize an image, but keep the same aspect ratio, set `h`, and set `constraint: on` to constrain the aspect ratio. E.g.
-
-```mermaid-example
-flowchart TD
-  %% My image with a constrained aspect ratio

-# @mermaid-js/layout-tidy-tree
-
-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';
-
-mermaid.registerLayoutLoaders(tidyTreeLayouts);
-```
-
-### With CDN
-
-```html
-<script type="module">
-  import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@11/dist/mermaid.esm.min.mjs';

-## 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
