{"version":"1.0","type":"rich","title":"Points on World Map","description":"This example displays global city populations as semi-transparent circles overlaid on a world map. The map uses a natural Earth projection rendered with D3’s `geoNaturalEarth1` and `geoPath`, with graticule and land/interior outlines. The `topojson` library processes world-atlas boundaries. City coordinates and populations come from a CSV, scaled by a square-root scale to a maximum radius of 10 pixels. The visualization is built in React, using hooks to asynchronously fetch data and render the SVG scene.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/32c4ccbfb1a2498cafb8358fb5492712?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
