{"version":"1.0","type":"rich","title":"Assignment 2 USA map","description":"This example displays a choropleth-style map of the United States rendered as SVG paths. The code uses D3 v5’s `d3.geoAlbersUsa` projection and `d3.geoPath` to convert GeoJSON features into map outlines, with each state filled red and stroked blue. The geographic data comes from a remote US features JSON file fetched via `d3.json`. The visualization sets a fixed 700×700 canvas and demonstrates D3 map projection, path generation, and asynchronous data loading in a single page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ac8f0b772ef4a1893e1382237812f44?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
