Visualize population density

Use a variable binding expression to calculate and display population density.

In this example, we use the population and area variables to create a choropleth map that visually represents the population density.

Use events and feature states to create a interactive choropleth map.

This example shows how to add a polygon layer to the map using the polygon layer helper.

This tutorial shows how to add a GeoJSON polygon overlay to the map.

This tutorial shows how to add a styled GeoJSON overlay to the map, display a popup on click, and create a map legend.
