{"version":"1.0","type":"rich","title":"map exemple","description":"This choropleth map displays global population estimates, with countries shaded from light red to dark red according to their population size. The visualization uses `d3.geoMercator` for projection and `d3.geoPath` to render country boundaries from TopoJSON data loaded via `d3.json`, while population values come from a TSV file loaded with `d3.tsv` and mapped to colors using `d3.scaleLinear`. The map supports pan and zoom interactions through `d3.zoom`, and hover effects are styled with CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fcb3f77010d74aef96aacbe9d575d8ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
