US heat (choropleth) map

Using our mapping tool you can easily create heat (or as BI-centric folks like to call it, <a href="https://en.wikipedia.org/wiki/Choropleth_map">choropleth</a>) maps. You only need to set light and dark color, and if your areas/countries/states has value assigned, the map will automatically choose intermediate color corresponding its value.
