{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economy classification using an ordinal color scale. Users can zoom and pan the map, and hovering over a country displays its name in a tooltip. The visualization pairs TopoJSON world geography with tabular TSV data from the World Atlas, merging them via `d3.json` and `d3.tsv`. It renders with SVG paths through `d3.geoPath` and `d3.geoNaturalEarth1`, and includes a custom color legend built with D3’s general update pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e04dc0119ff74fcbb14b70bbb13d485a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
