The Choropleth component displays divided geographical areas shaded in relation to some data variable. It's build on top of primitives from the GeoMap component.
Using this component requires some knowledge about the
library, projections, geoJSON… please have a look at the

Like for GeoMap, you must pass an array of features
which determine the geometries to render on the map, then you pass
an array of data which, each datum is merged with its corresponding
feature using the
match property, the value is picked according
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
you'll have to pass the
features array to the
The responsive alternative of this component is
This component also have a canvas implementations,
ChoroplethCanvas, which should be used
when you have complex geometries as it offers better performance.
