{"version":"1.0","type":"rich","title":"Circle Chart","description":"This circle chart displays the populations of the 10 most populous countries from 2018 World Population Prospects estimates, with each country represented by a black circle whose x-position and radius correspond to its population. The SVG rendering uses d3.scaleLinear and d3.scaleBand to map population values and country names, with d3.axisBottom and d3.axisLeft providing labeled axes. The code loads data from a CSV file via d3.csv, converts population values from thousands, and appends circles using d3.select and d3.append, with a formatted tick label function replacing G with B for billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8d0db247303d43ce8cee05eb8ea5fc72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
