{"version":"1.0","type":"rich","title":"Fork of React & D3 Vibecoding Starter","description":"This example recreates Charles Minard’s classic 1812 Napoleon march chart, tracing army size against longitude for both the advance to Moscow and the retreat, with a temperature annotation at the coldest point. The D3.js v7 code uses `scaleLinear` for axes, `scaleOrdinal` for the advance/retreat color encoding, and `curveCatmullRom` line smoothing. A React wrapper in `app.jsx` uses a `ResizeObserver` to feed container dimensions into the D3 rendering pipeline, which builds axes, legend, and the line-and-circle marks. The data is loaded from a CSV via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f44834155744521bedb0c7a228c29b6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
