{"version":"1.0","type":"rich","title":"choropleph","description":"This choropleth map uses a spectral color scale to visualize the economic classification of each country, with a hover effect that fills the selected country in black and a legend displaying the ordinal color domains. Built with d3.geoPath and the geoNaturalEarth1 projection, it renders SVG paths from TopoJSON world-atlas data and merges additional TSV attributes. Interactive pan and zoom are provided by d3.zoom, while the color legend is constructed manually with circles and text using scaleOrdinal and schemeSpectral.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/549b4a4288a64055872fc8141f9f068d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
