{"version":"1.0","type":"rich","title":"CPSC 436V Week 7 - Map with Selectable Countries","description":"This example shows a choropleth map of world countries colored by income group, with interactive selection. Clicking a country highlights it and dims all others, while a legend allows filtering by income category; clicking again deselects. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for projection and rendering, d3.zoom for panning, and d3.scaleOrdinal with schemeSpectral for color mapping. Data comes from TopoJSON world-atlas and TSV metadata, rendered as SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/112bdf5cc2424543837aaf7b775d4b29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
