{"version":"1.0","type":"rich","title":"Points On a Map","description":"This visualization displays a world map with cities rendered as circles, where the radius of each circle is proportional to the city's population using a square-root scale. The map uses an equal-area natural Earth projection with graticules and land masses drawn via `d3.geoPath`, while city coordinates are projected through the same projection. City population data comes from a CSV file, and the visualization is built with React and D3 v6, rendering all elements as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3c67fd5d0bd4beda70741a10bfd94f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
