{"version":"1.0","type":"rich","title":"Choropleth Map with D3.js","description":"This choropleth map visualizes global income groups using a color scale based on the Spectral scheme. The map is rendered with SVG paths generated by D3.js’s `geoPath` projection, and the world country boundaries come from the `world-atlas` TopoJSON dataset. Users can zoom and pan the map via the `zoom` event, and a color legend displays the ordinal scale’s categories. Data is loaded from the TSV file, merged with geographic features, and country names and income groups appear on hover via tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/629f2b6b08904fcb88e7d91f60c303a3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
