{"version":"1.0","type":"rich","title":"Mass Crime Map with circle size corresponding to crime/population ratio","description":"This example displays a choropleth-style map of Massachusetts where each circle’s radius encodes the crime-to-population ratio, allowing quick comparison of crime rates across counties. The map uses a `geoAlbers` projection with `geoPath` to render the state boundary, while circles are positioned via `projection` and sized with `scaleSqrt`. Data comes from a CSV file and a TopoJSON file, loaded using `d3.csv` and `d3.json`. The visualization is built with React and D3 v5, rendering in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/532fd10a876b420ea9d19d86c3e68a13?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
