Circles on a map
✓ Published0🌍 Public
This visualization displays global population data for 2018 using circles overlaid on a natural Earth projection map. The circles, sized with a square root scale, represent population magnitudes, while a legend explains the scaling. A color legend and interactive zooming are also included. The code uses D3 v5 APIs like `geoPath`, `geoNaturalEarth1`, `scaleSqrt`, and `topojson.feature`, with data loaded from a CSV file and a TopoJSON world atlas. The visualization is rendered as an SVG within a React framework.
