How to create a heatmap layer in Leaflet

Learn how to create a heatmap layer in Leaflet JavaScript library using the leaflet-maptilersdk plugin.

In this example, the heatmap layer is zoom-compensated and as a result the blobs roughly maintain their size in world-scale as we zoom-in/out. Download the earthquake sample data.




Replace YOUR_MAPTILER_API_KEY_HERE with your actual MapTiler API key.
