{"version":"1.0","type":"rich","title":"Maps-Exemple","description":"This example displays a choropleth map of world countries colored by population estimates, with hover highlighting and zoom/pan interaction. It uses D3 v5’s `d3.geoMercator` projection and `d3.geoPath` to render SVG paths from TopoJSON data loaded from the world-atlas package, while population values and country names come from a supplementary TSV file. A linear `d3.scaleLinear` maps population magnitudes to a red color ramp, and the `d3.zoom` behavior applies transforms to all country paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c19868406f774d85a880d87bc34d3263?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
