This visualization presents a choropleth map of road accident deaths across Russian regions, with color-coded polygons indicating mortality rates and city markers overlaid on major population centers. Hovering over a region reveals its name and death count via a tooltip. The map is rendered using D3 v3’s `d3.geo.albers` projection and `d3.geo.path` on topojson data, while a `d3.scale.threshold` maps death values to a green-to-red color scale. Accident statistics come from a CSV file, and city coordinates are loaded from a TSV file.
