{"version":"1.0","type":"rich","title":"Map final project","description":"This choropleth map colors countries by their economic classification using a spectral color scale, with a hover effect to highlight individual nations and a legend showing the color-to-category mapping. Built with D3 v5, it loads geographic boundaries from a TopoJSON world atlas and income-group data from a TSV file, then projects them using the `geoNaturalEarth1` projection and renders paths with `geoPath`. The visualization implements interactive zooming via the `zoom` event and a custom `colorLegend` component, with the map’s ocean rendered as a styled sphere path.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/463073c3bab84c14be421bc948c15fa4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
