{"version":"1.0","type":"rich","title":"D3 - World Choropleth","description":"This example displays a world choropleth map of population in 2023, using a Mercator projection and a yellow-to-red sequential color scale to represent each country’s population. The map is rendered as SVG paths, with a tooltip that appears on hover showing the country name and population. The code loads GeoJSON and CSV data via D3’s `d3.queue` and `d3.json`/`d3.csv` APIs, and it builds the choropleth using `d3.geoPath` with a projected path generator. A legend is added using the `d3.legend` library, and the project utilizes D3 v4, `d3-scale-chromatic` for the color interpolation, and `d3-geo-projection` for the map projection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fbc44d7ab30f4be2917db49e98355b14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
