GeoMap

@nivo/geomap

This component can be used to draw maps, it takes an array of features which determine the geometries to render on the map. It can be used to build more complex maps such as the Choropleth.

Using this component requires some knowledge about the d3-geo library, projections, geoJSON… please have a look at the official d3 documentation for further information.

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 ResponsiveGeoMap, it also offers a canvas implementations, see GeoMapCanvas.
