{"version":"1.0","type":"rich","title":"Untitled","description":"A choropleth of the United States visualizes violent crime rates per state from 1999 to 2019. The map uses SVG circles positioned via `d3.geoAlbersUsa` and `d3.geoPath` to represent state-level crime counts, with circle size and color encoded through `d3.scaleLinear`. Users select a year and crime type (e.g., homicide, robbery) from dropdown menus, triggering a redraw of the map with updated data. The visualization loads state geometries from `us-states.json` and coordinates from `states_lon_lat.json`, with data from the `estimated_crimes_1999_2019.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0a85336b6d204156800c57505f434dc8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
