{"version":"1.0","type":"rich","title":"Chloropleth Map","description":"This choropleth map visualizes global income groups by country, using a spectral color scale to differentiate categories. Built with D3 version 5, the map employs `d3.geoNaturalEarth1` for projection and `d3.geoPath` to render country boundaries from TopoJSON data, with attributes joined from a TSV file. The visualization supports zoom interactions via `d3.zoom`, displays hover tooltips with country names and income groups, and includes a custom color legend rendered from SVG circles and text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d68bc56e7c042b3a8793e6017515492?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
