{"version":"1.0","type":"rich","title":"Ancient Visualizations","description":"This visualization recreates Minard's classic map of Napoleon's 1812 march to Moscow, showing army size through path width, advance and retreat directions in tan and blue, and a temperature chart during the retreat. The React app loads CSV data via `d3.csv` and renders an SVG using scales from `d3.scaleLinear` and line generators from `d3.line`. City markers, a legend, and temperature annotations support the narrative of troop attrition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3fa6a968c0da44588cc64bd94b5b994d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
