{"version":"1.0","type":"rich","title":"Assignment 9: Proportional Map","description":"This map of the United States uses green circles of proportional size to depict the relative housing cost index for each state, with a legend indicating values of 100, 200, and 300. The visualization renders the state outlines as an SVG path from TopoJSON data, while the data-driven symbols are drawn from a centroid point layer. The code employs d3.geo.path and d3.scale.sqrt for the projection and proportional scaling, loading the dataset from a CSV file to define the circle radii.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/26c0fc48bb174f3298448176cd684fa4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
