This example shows a world map where countries are rendered in light green and turn red on hover, while a blue sphere outlines the globe. It demonstrates cheap interaction tricks using a zoom tool and simple CSS hover effects. The visualization relies on D3 v5 and the TopoJSON library to load and project geographic data from the world-atlas package, using a equirectangular projection and SVG paths for rendering. A title element displays the country name on hover, sourced from a TSV metadata file.
