This example displays a world map with semi-transparent circles sized to represent video views, using data from a CSV of course participants. The visualization uses a Natural Earth projection via `geoNaturalEarth1` and renders geographic features with `geoPath` and `geoGraticule`, while the circles use `scaleSqrt` mapped to the `nplay_video` field. Country boundaries come from World Atlas TopoJSON, and the React-based component structure leverages the `useWorldAtlas` and `useDataViews` hooks to load and parse the data.
