Allow Heat Maps from Esri demographic data

[YonatanZvi]

Using ArcGIS Online it would be very helpful to have a feature that allows users to create heat maps using the Esri demographic data layers. Currently it only allows heat mapping from user uploaded data. Working in Commercial RE clients often have a few key parameters (income, population density, etc.) they want to know during the site selection process, and being able to present them with a heat map of those parameters would make our job much easier, and ensure Esri's ability to compete in the rapidly advancing GIS marketplace.
