ChoroplethCanvas

@nivo/geomapcanvas

A canvas implementation of the Choropleth component, should be used used when you have complex geometries as it offers better performance than its SVG counterpart.

Please note that because the features file is pretty huge, it's not included in the generated code, you can find the file used for this example here, you'll have to pass the features array to the features property.

The responsive alternative of this component is ResponsiveChoropleth.
