/**
 * Represents the Kendo UI for Angular Sankey diagram component.
 *
 * The Sankey diagram visualizes flow data between different categories or stages.
 * It displays nodes connected by links where the thickness of each link represents the flow value.
 *
 * @example
 * ```ts
 * import { Component } from '@angular/core';
 *
 * @Component({
 *   selector: 'my-app',
 *   template: `
 *       <kendo-sankey [data]="data">
 *       </kendo-sankey>
 *   `,
 * })
 * export class AppComponent {
 *     public data: SankeyData = {
 *         nodes: [
 *           { id: 1, label: { text: 'Linux' } },
 *           { id: 0, label: { text: 'iOS'} },
 *           { id: 2, label: { text: 'Mobile' } },
 *           { id: 3, label: { text: 'Desktop' } },
 *         ],
 *         links: [
 *           { sourceId: 0, targetId: 2, value: 1 },
 *           { sourceId: 1, targetId: 2, value: 2 },
 *           { sourceId: 1, targetId: 3, value: 3 },
 *         ],
 *       };
 * }
 * ```
 *
 * @remarks
 * Supported children components are: {@link SankeyCustomMessagesComponent}, {@link SankeyLabelsComponent}, {@link SankeyLegendComponent}, {@link SankeyLinksComponent}, {@link SankeyNodesComponent}, {@link SankeyTitleComponent}, and {@link SankeyTooltipComponent}.
