{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive filtering","description":"A choropleth map of global economies color-coded by development category, with an interactive legend that filters highlighted countries by clicking category swatches. Built with D3 v5, it combines `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.zoom` for panning and zooming the SVG-rendered map, while `d3.scaleOrdinal` and `schemeSpectral` assign colors from world-atlas TopoJSON data. Clicking a legend item dims non-matching countries and toggles the selection; tooltips show country names and values via SVG `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/46d971756fdf4f80ae637f22879eb56a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
