This visualization maps global tree cover loss by country, using a chloropleth color scale from green to red to indicate the percentage change between 2000 and 2010. The code fetches geographic boundaries from the VisionCarto World Atlas and joins them with CSV data on tree cover extent, applying a D3 Mercator projection and `geoPath` for rendering. Country colors are computed with `interpolateRdYlGn` based on the calculated land-area delta, with stroke outlines for boundaries.
