{"version":"1.0","type":"rich","title":"Points on a Map","description":"This visualization displays a world map with cities plotted as scaled circles representing population. The map uses the Natural Earth projection with graticules, country boundaries, and interiors rendered via D3's `geoPath` and `geoNaturalEarth1` projection. City positions come from a CSV file, and circle radii are scaled using D3's square-root scale (`scaleSqrt`) based on population data. The visualization is built with React and renders SVG marks, including land masses, a sphere outline, and graticule lines, all styled with a clean grayscale aesthetic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d83f0547af3144318a0501bed813dba9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
