{"version":"1.0","type":"rich","title":"SF Arrests","description":"This visualization maps arrests in San Francisco over the past week, using a conic equal-area projection to render neighborhood boundaries and street lines as the basemap. Each arrest is plotted as a semi-transparent circle, with neighborhoods highlighting on hover to show district names. The code loads GeoJSON basemap and street data via `d3.json`, queries the Socrata Open Data API for arrest records with a date range filter, and draws all elements as SVG paths and circles using `d3.geoPath` and standard D3 selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f596517dc434fdf87919ce4217d4c6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
