{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map colors world countries by economic grouping, using a spectral color scale with a custom legend. The visualization reacts to user zoom and pan gestures, redrawing country boundaries through D3’s `geoPath` and `geoNaturalEarth1` projection. Country data merges TSV attributes with TopoJSON geometry via `topojson.feature`, and hovering any country highlights it in red, while a tooltip shows its name and economic category. The project relies on D3 v5’s `scaleOrdinal`, `schemeSpectral`, and the `zoom` event helper for interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09d73f228cd746449704b50e180987d0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
