{"version":"1.0","type":"rich","title":"Accidents on the Road - Choropleth","description":"This choropleth maps road accident deaths across Russian regions, using a threshold color scale from light green to dark red, and includes interactivity where hovering highlights a region and displays its name and fatality count on a tooltip. It also plots major cities as points and includes a vertical legend. Built with D3.js v3, it uses the `d3.geo.albers` projection and `d3.geo.path` to render the map geometries from TopoJSON, while `d3.csv` and `d3.tsv` load the accident and city data, and SVG shapes, transitions, and the `d3.select` API handle the visualization and mouseover effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d8ffab1e14f4be0860aedcd27e0a951?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
