{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by their economic classification, with a color legend showing ordinal categories from the Spectral scheme. The visualization loads world geometry from TopoJSON and joins it with tabular data from a TSV file. Using d3.geoPath with a geoNaturalEarth1 projection, it renders SVG paths that support zooming via d3.zoom. Hovering highlights individual countries, while a custom colorLegend component displays the color scale with circles and text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a8890b06e3e047379b6d0ff6fa1e9eca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
