{"version":"1.0","type":"rich","title":"Accidents on the Road - Choropleth","description":"This choropleth maps road accident deaths across Russian regions, using a color scale from light yellow to dark red to indicate increasing fatality counts. It loads geographic boundaries from a TopoJSON file and accident statistics from a CSV, joining them by region code. The visualization uses D3 v3 with `d3.geo.albers` projection, `d3.geo.path` for rendering SVG paths, `d3.scale.threshold` with ColorBrewer palettes, and `queue()` for asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b83f87901d85d46e7ff4d1890f939e8f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
