 * > This is a **legacy component**. It relies on an underlying widget as part of our migration to native web components.

 *
 * The Size Slider component is intended for authoring and exploring data-driven visualizations in any
 * layer that can be rendered with a [SizeVariable](https://developers.arcgis.com/javascript/latest/references/core/renderers/visualVariables/SizeVariable/).
 *
 * See the image below for a summary of the configurable options available on this slider.
 *
 * ![Size Slider with annotations](https://developers.arcgis.com/javascript/latest/assets/references/core/widgets/sliders/sizeslider-labels.avif "Size Slider with annotations")
 *
 * The [updateFromRendererResult()](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-slider-size-legacy/#updateFromRendererResult) method can be used to intelligently populate slider properties including
 * [max](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-slider-size-legacy/#max), [min](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-slider-size-legacy/#min), [size visual variable](https://developers.arcgis.com/javascript/latest/references/core/renderers/visualVariables/SizeVariable/)
 * intervals, and the slider's histogram after the renderer has been created from the result of the
 * [createContinuousRenderer()](https://developers.arcgis.com/javascript/latest/references/core/smartMapping/renderers/size/#createContinuousRenderer) method.
 *
 * ```js
 * const sizeRendererCreator = await import("@arcgis/core/smartMapping/renderers/size.js");
 * const viewElement = document.querySelector("arcgis-map")!;
 * const sizeSlider = document.querySelector("arcgis-slider-size-legacy")!;
 *
 * const featureLayer = new FeatureLayer({
 *   url: "https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/USA_Major_Cities_/FeatureServer/0",

 *
 * await viewElement.viewOnReady();
 * viewElement.map?.add(featureLayer);

 *
 * const histogramResult = await histogram({
 *   ...params,
 *   numBins: 30,
 * });
 *
 * sizeSlider.updateFromRendererResult(rendererResult, histogramResult);
 * ```
 *
 * This slider should be used to update a [size visual variable](https://developers.arcgis.com/javascript/latest/references/core/renderers/visualVariables/SizeVariable/)
 * in a layer's renderer. It is the responsibility of the app developer
 * to set up event listeners that update the size variable of the appropriate renderer.
 *
 * ```js
 * const updateRendererFromSlider = () => {
 *   const renderer = featureLayer.renderer?.clone();
 *   if (!renderer || !("visualVariables" in renderer) || !renderer.visualVariables?.[0]) {
 *     return;
 *   }
 *
 *   const sizeVariable = renderer.visualVariables[0];
 *   const updatedSizeVariable = sizeSlider.updateVisualVariable(sizeVariable);
 *   if (!updatedSizeVariable) {
 *     return;
