 * The Classed Color Slider component is designed for authoring and exploring data-driven visualizations in any
 * layer that can be rendered with color in a [ClassBreaksRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/ClassBreaksRenderer/).
 *
 * <span id="image-annotations"></span>

 *
 * ![Classed Color Slider with annotations](https://developers.arcgis.com/javascript/latest/assets/references/core/widgets/sliders/classedcolorslider-labels.avif "Classed Color Slider with annotations")
 *
 * The [updateFromRendererResult()](https://developers.arcgis.com/javascript/latest/references/core/widgets/smartMapping/ClassedColorSlider/#fromRendererResult) method can be used to intelligently populate slider properties including
 * [max](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-slider-classed-color-legacy/#max), [min](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-slider-classed-color-legacy/#min), the [classBreakInfos](https://developers.arcgis.com/javascript/latest/references/core/renderers/ClassBreaksRenderer/#classBreakInfos) configuration,
 * and the slider's histogram after the renderer has been created from the result of the
 * [createClassBreaksRenderer()](https://developers.arcgis.com/javascript/latest/references/core/smartMapping/renderers/color/#createClassBreaksRenderer) method.
