{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map displays world economies using color-coded countries, with an interactive legend that filters the map by clicking on a category while dimming non-matching regions. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for the map projection, `scaleOrdinal` with `schemeSpectral` for coloring, and `zoom` for panning. Hovering reveals country names via `title` elements. Data comes from the world-atlas TopoJSON dataset, enriched with a TSV file of economy classifications. The SVG rendering synchronizes legend and map states through shared `selectedColorValue` events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/19d6dfba9a3f42f5a63f0fb11fa7bf19?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
