Create a Metric Heatmap Layer on a Map

Use a heatmap layer to show the intensity of a measure value for each data point on a map visualization.

When you add a measure column for Color in the Grammar pane, you can change the type of aggregation to apply. The aggregation type defines how the metric values for overlapping or identical data points on the map are combined when mapping them to the colors used in the heatmap.
