{"version":"1.0","type":"rich","title":"Fork of Fork of The map of soldier data visualization in war - Napoleon's Russian campaign","description":"This D3.js v7 visualization recreates Charles Minard’s 1869 flow map of Napoleon’s 1812 Russian campaign, showing troop strength as the width of tan (advance) and dark gray (retreat) area paths that narrow from 422,000 to 400 survivors. Cities, rivers, and a temperature chart plotting the retreat’s falling degrees accompany the geographic map, with hover tooltips on army paths and city markers. The implementation uses `d3.csvParse` for troop, city, river, and temperature data, `d3.area` with `curveLinear` to generate the troop flows, and `d3.group` to organize data by army group and direction. Animated transitions and responsive SVG rendering complete the interactive Tufte-inspired design.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8d801af4db8b4a6a968edbbe62d80591?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
