Analyzing Data in a Density Map Visualization

The Density Map visualization allows you to display your data on an interactive map as areas color-coded based on the population density of locations on the map. For example, a designer can create a Density Map visualization to display areas with a high concentration of stores in red, and areas with a low concentration of stores in blue.

You can:

Filter data to display only the locations you select
Filter data to display all locations except for those you select
Zoom in, zoom out, and pan across the map to customize your display
Display Information Windows with additional information about a location when the user hovers the cursor over an area in the visualization.
