{"version":"1.0","type":"rich","title":"The map of soldier data visualization in war - Napoleon's Russian campaign","description":"This map visualizes Napoleon’s 1812 Russian campaign, showing the army’s advance and retreat as a flow line whose thickness encodes the surviving troop count. The path splits into three groups, with city labels marking locations, while a separate temperature chart plots the frigid retreat conditions. Built with D3 v7, the visualization renders SVG elements, using `d3.scaleLinear` for axes, `d3.line` for the temperature curve, and `d3.group` to organize the data by army group and direction. The `index.js` file parses embedded CSV data for troops, cities, and temperatures, with CSS styling for the tooltip and legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b14ca51cbd024984a9591bd8bc2a373a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
