Hovering over a bubble reveals a tooltip with the country name, region, and population. The visualization uses D3 v7's `scaleLinear` for axes, `scaleOrdinal` with `schemeCategory10` for regional coloring, and `axisBottom`/`axisLeft` for tick marks, loading data from a local CSV file into an SVG rendered through D3's selection API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/995ecc68f63a4018827828ca9299d2a7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
