This world map visualizes global population distribution, with countries shaded in increasingly deep reds to indicate higher 2022 population figures. The visualization loads geographic boundaries from the visionscarto-world-atlas TopoJSON file and joins it with population data from a CSV file. Using D3’s `geoNaturalEarth1` projection, `geoPath`, and `scaleSequential` with `interpolateReds`, it renders each country as a filled path. A graticule and outline provide geographic context, while the map fetches and processes the atlas data asynchronously via `fetch` and `topojson.feature`.
