Circles on a Map
✓ Published0🌍 Public
This map visualizes global population estimates for 2022, with each country represented by a circle sized by its population and positioned at its centroid. The visualization uses D3's `geoNaturalEarth1` projection and `geoPath` to render the map, while `scaleSqrt` scales the circle radii. A size legend and color legend, built with reusable D3 modules, explain the encoding. Population data comes from a UN CSV file, and the map uses TopoJSON from the VisionsCarto World Atlas.
