{"version":"1.0","type":"rich","title":"Fork of map exemple","description":"This example shows a world map where each country is colored according to its population, using a threshold color scale and the D3.js library. The map uses a Mercator projection via `d3.geoMercator`, with country boundaries drawn using `d3.geoPath` from TopoJSON data. Hovering over a country triggers a transition that highlights it and dims others, while the underlying data comes from a CSV file. The code relies on `d3.queue` to load external data and uses `d3.scaleThreshold` with `d3.schemeBlues` for the color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d815a286205e46d7b27845004cf48432?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
