{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map displays global economic classifications by country, with a color legend encoding each category. Clicking a legend item filters the map, dimming non-matching countries while highlighting the selected group. Hovering reveals country names and values via tooltips. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for SVG map rendering, `scaleOrdinal` with `schemeSpectral` for colors, and `zoom` for panning. Data comes from TopoJSON world-atlas merged with TSV metadata.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/beeeee3a47fe4dbe8665d64d0e0912c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
