Colors - Match Map Layer Symbolization

When working with customers, a common request I get is to have the colors of a graph (most typically this happens with a pie chart but could be with any type I suppose) match the symbolization of the features on the web map that the pie piece represents. (https://community.esri.com/ideas/5989 as an example of these types of requests)

The issue names no files, tests, or entry points. Start by reviewing the linked ArcGIS community request and how Cedar receives map-layer symbolization alongside chart data. Done should mean chart colors, including pie-chart segments, match the symbolization of the represented web-map features.
