{"version":"1.0","type":"rich","title":"4","description":"A population bubble chart displays projected and current population data for countries, using circle size to encode the 2022 population and color to distinguish categories. The visualization includes a custom tooltip that reveals country names and population values on hover. It loads JSON data from a GitHub-hosted dataset via `d3.json`, and renders the chart using `d3.select`, `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleOrdinal` within an SVG canvas, with event listeners for mouse interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e3858c9aeab04faca24a647fa41bec94?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
