{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map displays global economic classifications by country, with a color legend that doubles as an interactive filter. Clicking a legend item dims all countries except those matching the selected category, while hovering over the map highlights a country in red. The visualization uses D3 v5’s `scaleOrdinal` with a spectral color scheme and `geoPath` with the Natural Earth projection to render the map. Country boundaries and income data come from the world-atlas TopoJSON, and spatial interaction is handled by D3’s `zoom` event system.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e035421bcb124ac39db7edf0cbf11781?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
