{"version":"1.0","type":"rich","title":"Circles on a Map","description":"This visualization maps higher education providers across the UK, using circles positioned at geographic centroids to represent the number of students with known disabilities. The circle area scales with this population value via a square-root scale, and a size legend with formatted ticks clarifies the mapping. Users can pan and zoom with d3.zoom, while hovering over region paths highlights them. The code uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering, and loads data from a CSV describing provider characteristics joined to TopoJSON world boundaries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89d8f730db424463af38546d217ea4c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
