{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes global income groups by coloring each country according to its `income_grp` attribute, using a spectral color scale (`d3.schemeSpectral`). The map shows a natural Earth projection rendered with `d3.geoPath`, with hover interactions highlighting countries in red. Built with React and D3 v6, it loads world boundary data from the `world-atlas` package via TopoJSON and TSV files, and includes a custom color legend component. The visualization supports zooming through a zoom behavior API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f810cfc22f404c84974828e419712117?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
