{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map renders country boundaries and graticules from World Atlas TopoJSON, with city points sized by population using a square-root scale. Built with React and D3 v5, it uses `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` to draw shapes, while circles are positioned by projecting latitude and longitude coordinates. The SVG output is styled with a light gray land fill and semi-transparent teal city markers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99582bfed54141aba58911105b64b231?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
