{"version":"1.0","type":"rich","title":"The map of soldier data visualization in war - Napoleon's Russian campaign","description":"A faithful recreation of Charles Minard's 1869 flow map depicts Napoleon's 1812 Russian campaign, showing the army's advancing and retreating paths with path widths proportional to troop counts, cities, rivers, and a temperature chart of the winter retreat. Built with D3.js v7, it uses `d3.area()` for the troop-flow bands, `d3.csvParse()` for data ingestion, and SVG rendering with hover tooltips. Data includes troop survival counts, geographic coordinates, and temperature readings throughout the campaign.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/08e80192ca4c48e3a06642405ac83a1e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
