{"version":"1.0","type":"rich","title":"Choropleth Map.js","description":"This choropleth map colors countries by their economy classification using an ordinal color scale with a spectral palette. A hover effect highlights individual countries, and a custom legend displays the color categories. The visualization loads world geometry from TopoJSON and joins it with tabular TSV data, rendered as SVG paths via `d3.geoPath` and a natural Earth projection. Interactive pan and zoom are enabled through `d3.zoom`, while the legend and map styling are built with D3’s selection and data-join methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/19cc413036af4fa9af627ccac53ccb20?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
