{"version":"1.0","type":"rich","title":"World Map","description":"This world map visualizes global population distribution by income group, using color to encode each country's economic classification. The map is rendered with D3 v5’s `d3.geoMercator` and `d3.geoPath`, projecting GeoJSON country boundaries from the world-atlas package. A color legend, built with custom D3 code, maps income categories to a sequential red color scale (`d3.schemeReds`), while interactive zooming is enabled via `d3.zoom`. Population data from the included CSV is not directly displayed but informs the visualization’s narrative.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37c82125204e4adbaa445b48c78f66fb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
