{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map visualizes world countries colored by economic classification, with an interactive color legend that filters the map when clicked. Hovering a country reveals its name and value via a tooltip, and the map supports zooming and panning. The visualization uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` for the map, while `scaleOrdinal` with `schemeSpectral` maps data values to colors. Data is loaded from the World Atlas TopoJSON and TSV files, and filtering updates both map and legend opacities in real time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/868e679a37b14456b2cae7b5978e9150?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
