/**
 * Layout Module
 *
 * Provides automatic graph layout algorithms for dialogue trees.
 * Uses the Strategy pattern to allow swappable layout algorithms.
 *
 * ## Quick Start
 *
 * ```typescript
 * import { layoutRegistry, applyLayout } from './layout';
 *
 * // Apply default layout (dagre)
 * const result = applyLayout(dialogue);
 *
 * // Apply specific layout
 * const result = applyLayout(dialogue, 'force');
 *
 * // With options
 * const result = applyLayout(dialogue, 'dagre', { direction: 'LR' });
 *
 * // List available layouts
 * console.log(layoutRegistry.list());
 * ```
 *
 * ## Adding Custom Layouts
 *
 * See LAYOUT_STRATEGIES.md for documentation on creating custom layouts.
 *
 * @module layout

import { DialogueTree } from '../../types';

/**
 * Apply a layout algorithm to a dialogue tree
 *
 * @param dialogue - The dialogue tree to layout
 * @param strategyId - Optional strategy ID (defaults to 'dagre')
 * @param options - Optional layout configuration
 * @returns Layout result with updated dialogue and metadata
 *
 * @example
 * ```typescript
 * // Default dagre layout
 * const result = applyLayout(dialogue);
 *
 * // Horizontal dagre layout
 * const result = applyLayout(dialogue, 'dagre', { direction: 'LR' });
 *
 * // Force-directed layout
 * const result = applyLayout(dialogue, 'force');
 *
 * // Grid layout
 * const result = applyLayout(dialogue, 'grid');
 * ```
