{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This interactive choropleth map displays global income groups using a natural Earth projection, with a linked color legend that filters highlighted countries on click and enables zooming via `d3.zoom`. It loads world topology from the World Atlas TopoJSON and tab-separated metadata, processing features through `d3.geoPath` and `d3.geoNaturalEarth1`. Colors are assigned with `d3.scaleOrdinal` and `d3.schemeSpectral`. The legend, built with custom SVG groups, toggles selection states and updates opacity, while the map’s sphere and country paths respond to hover and interactive filtering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d621e6fc4eb649b787d3d0b7669039e7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
