{"version":"1.0","type":"rich","title":"Untitled","description":"This visualization shows the under-18 population living in poverty across U.S. counties in 2014, using red semi-transparent bubbles overlaid on a map. Bubble size encodes population via a square-root scale, and tooltips display county names and populations on hover. The map is built with D3.js, using `d3.geo.path` for rendering topojson shapes, `d3.svg.arc` for bubble outlines, and `d3.json` to load data from a GitHub-hosted JSON file. The SVG output animates state borders and bubble hover effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/80f3cfbb158b4f2cad60ddd6cb12f27d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
