{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries of the world according to their economic classification, using a spectral color scale. The visualization is rendered as an SVG and supports zooming. Built with D3 v5, it leverages `geoPath` and `geoNaturalEarth1` for map projection, and `scaleOrdinal` with `schemeSpectral` for coloring. Data comes from the world-atlas package (50m TSV and JSON files), loaded via `loadAndProcessData`, with countries displayed as paths and a custom legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b0bc79bfaeb47b6a9b548bc605d2780?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
