{"version":"1.0","type":"rich","title":"Exercise","description":"This visualization shows a choropleth map of countries colored by their economy type, with an interactive legend that filters and highlights selected categories. The map uses a natural Earth projection with d3.geoPath, while the view supports pan and zoom via d3.zoom. Data comes from world-atlas TopoJSON with a TSV mapping country codes. Colors are assigned through d3.scaleOrdinal with the Spectral scheme, and clicking legend items toggles dimming of non-selected countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36b71070f2b44578a389d81a76852635?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
