Description
The InfographicsCarousel widget requests for GeoEnrichment data of a given location, and visualizes the results in a collection of Infographics. This sample allows users to click any location on the map and returns the GeoEnrichment data (a one variable summary and an age pyramid) of a 5-mile driving buffer area. Use the "previous" and "next" button to switch between different info graphics.
GeoEnrichmentis a subscription based service available through ArcGIS Online. Log-in credentials are always required when executing a GeoEnrichment task.
