{"version":"1.0","type":"rich","title":"d3 Choropleth Map","description":"This d3 Choropleth Map visualizes world countries colored by their economic classification from a World Atlas dataset. It uses an SVG rendering with a natural Earth projection and a spectral color scale for the legend. The code employs `d3.geoPath`, `d3.geoNaturalEarth1`, and `topojson.feature` to process and draw the map, while `d3.scaleOrdinal` and `schemeSpectral` define the color categories. A custom legend component displays the color scale with circles and labels, and hovering a country turns it red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0355cfed38f14562b09fd7d4aa35516e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
