{"version":"1.0","type":"rich","title":"Project | last part","description":"This visualization is a choropleth map of world countries colored according to a color scale derived from a categorical attribute, with a legend allowing interactive filtering of highlighted countries. The map uses the D3 geo projection API (`geoEquirectangular` with `geoPath`) to render country boundaries as SVG paths from TopoJSON data merged with CSV attributes. The legend, built with D3's ordinal color scale and the `schemeYlOrRd` color scheme, responds to clicks to toggle a selected category, which dims non-matching countries. The map also implements a zoom interaction via D3's `zoom` event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c0b15711fc14fb9911f71f10bca6cc6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
