{"version":"1.0","type":"rich","title":"Mass Crime Map with circle size corresponding to crime/population ratio","description":"This map of Massachusetts towns shows crime rates as circles overlaid on geographic boundaries, with circle size scaled to each town's crime-to-population ratio. Using React and D3 v5, the visualization projects GeoJSON features onto an SVG canvas via d3.geoPath with a geoAlbers projection, while d3.scaleSqrt maps crime rates to circle radii. Crime data comes from the FBI’s 2016 table, and geographical boundaries derive from MassGIS shapefiles converted to TopoJSON. Hovering reveals city, county, and exact crime rate in the tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d704c9b0fe7f438c90a59b52e72d37c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
