{"version":"1.0","type":"rich","title":"Fork of Fork of Choropleth Map","description":"This choropleth map colors countries by their economy classification using a spectral color scale, with hover highlighting and a circular legend showing the categorical values. The visualization loads world topology from the world-atlas TopoJSON dataset and joins it with TSV metadata. Built with D3 v5, it uses `d3.geoNaturalEarth1` projection, `d3.geoPath` for rendering SVG paths, `d3.zoom` for pan and zoom, and `d3.scaleOrdinal` with `schemeSpectral` for color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a290118ee2a24e708587c54528f44f97?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
