Leaflet.js and the Esri-leaflet API are being used to consume a REST ESRI feature layer service hosted on ArcGIS Online. The feature layer originates as a personal geodatabase using ArcMap 10.5.1. Leaflet.markercluster.js is being used to resolve a cartographic and UI problem posed by several dozen polygon features that share the same geographic extent and thus obscure each other from view.
