{"version":"1.0","type":"rich","title":"Accidents on the Road - Choropleth","description":"A choropleth map of Russia colors each federal region according to the rate of car accidents per capita, using a threshold scale with ranges like low, medium, and high. Hovering over a region highlights it and reveals a tooltip with the region’s name and value. The visualization also labels major cities with circles. Built with D3 v3, it uses `d3.geo.path`, `d3.geo.albers`, and TopoJSON for map rendering, while reading data from CSV and TSV files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f57d8d395dbf4eb985bdc0d5f1602193?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
