Feature Cluster/Reduction - Render symbol color by size

ChrisSmith7

Hello,

I understand featureReduction in v4 isn't yet on par with v3, so in v3, is it possible to render cluster colors by size? For example:

https://developers.arcgis.com/javascript/3/jssamples/fl_clustering_toggle.html

...rather than using Drawing/Rendering Info from the service:

https://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/socal_precincts_points_2008/FeatureServer//layers

...I'd like to have a renderer based on cluster size as determined by featureReduction. Something more like this:

https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.388.html

Is this possible?

Thanks!

Inspecting the DOM, I can see there is a way I could loop over the radius vals and roll my own classification:

It would be preferable to take advantage of the API, though, if it's supported.
