{"version":"1.0","type":"rich","title":"Choropleth Map w Interactive Filtering","description":"This choropleth map displays global income groups, color-coded using a spectral scale and an interactive zoom projection built with D3’s geoNaturalEarth1 projection and geoPath. The map renders country boundaries from World Atlas TopoJSON and TSV data, with a custom legend generated by colorLegend.js. Users can pan and zoom via the zoom overlay, while hovering over a country highlights it in gray and reveals its name and income group in a tooltip. The visualization demonstrates SVG-based DOM manipulation and event handling through D3’s selection and event APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9387a584f9ad41938359e5b83a1ec247?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
