Heatmap Layer

DEPRECATED

The HeatmapLayer component was deprecated on May 27, 2025 and will be sunset in May 2026. Google recommends migrating to third-party library integrations like deck.gl, which offers a HeatmapLayer implementation. Learn more about the deprecation.

Use the HeatmapLayer component to depict the intensity of data at geographical points on the map. Make sure to include the visualization library in the libraries prop of the GoogleMap component.

Options

You can pass a HeatmapLayerOptions object to the options prop to configure your heatmap layer. Note that for convenience you can use LatLngLiterals if you wish for the locations.
