This choropleth map visualizes a sample “Digital Access Score” by country, using a blue color scale to represent the mock 0–100 indicator values. Built with D3 v7, the visualization uses a Natural Earth projection and `d3.geoPath` to render countries from TopoJSON data. It displays a graticule grid on a soft blue ocean sphere, with an interactive hover tooltip that reveals each nation’s score and name. The example demonstrates linking geographic boundaries with attribute values, with a legend and header clarifying the illustrative nature of the data.
