Geoenrichment - Infographic

Description

The Infographic widget requests for GeoEnrichment data of a given location, and visualizes the results in a Infographics consisting of properly formatted charts and/or tables. This sample allows users to click any location on the map and returns the GeoEnrichment data (an age pyramid) of a 1-mile ring buffer area.

GeoEnrichment is a subscription based service available through ArcGIS Online. Log-in credentials are always required when executing a GeoEnrichment task. For demo purpose, this sample uses a helper method to define a proxy for a set of resources. All requests to geoenrich.arcgis.com are routed to the specified proxy url.
urlUtils.addProxyRule({
  urlPrefix: "geoenrich.arcgis.com",
  proxyUrl: "/sproxy"
});
When writing your own apps, remove this part from the code so your users will be able to sign in with their own credentials.
