{"version":"1.0","type":"rich","title":"Assignment 8 Maps ","description":"This choropleth map displays global GDP distribution, coloring countries by their Gross Domestic Product in billions of USD using a sequential green color scale. Built with D3 v7, it loads TopoJSON world atlas data and renders it as SVG paths via `d3.geoPath` with a Natural Earth projection. A threshold-based color scale (`d3.scaleThreshold`) maps GDP ranges to colors, while hover interactions trigger tooltips showing country names and GDP values. A legend explains the color bins, and gray indicates missing data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/33730283a2b944f897a1da4266b7c296?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
