Deck.gl GeoJSON Choropleth
A country choropleth fed straight from a GeoJSON feature collection — Deck.gl's GeoJsonLayer parses the polygons (and multi-polygons), shades each one by a value picked from the feature's properties, and renders the whole world at GPU speed. The fill colour is interpolated throug

When to use this template
This visualization helps compare a single continuous metric across distinct geographic regions, making spatial patterns and disparities immediately apparent. Analysts use it to identify areas of high or low values, observe regional trends, and understand the geographic distribution of a phenomenon.
- Geographic data represented as GeoJSON polygons or multi-polygons.
- One continuous, quantitative metric associated with each geographic region.
- Data where spatial distribution or regional comparison is the key insight.
- Regions are distinct, non-overlapping, and cover a defined area.
- Suitable for large numbers of regions, leveraging GPU rendering for interactivity.
- Requires a unique identifier for each geographic feature to link data.
