A world map visualizes the global distribution of Netflix movie production by country, with individual nations colored on a blue sequential scale based on the count of titles associated with them. The example uses d3-geo’s `geoNaturalEarth1` projection and `geoPath` to render world boundaries, while `topojson-client` converts the TopoJSON atlas data into GeoJSON features. Movie counts are aggregated from a bundled CSV file, and interactive tooltips display the exact number per country on hover.
