{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"A world map displays cities with populations over 50,000 as semi-transparent circles, with point size proportional to the number of crimes. The visualization uses a natural Earth projection via d3.geoNaturalEarth1 and d3.geoPath, rendering spheres, graticules, and land boundaries from World Atlas TopoJSON data. Circle radii are scaled using d3.scaleSqrt, with city coordinates and crime statistics loaded from a CSV file. The React component architecture leverages hooks to fetch and process data asynchronously.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e7e8b7d915af472fb890f19f7bed11e5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
