Circles sized with `d3.scaleSqrt` mark the number of video plays at each recorded latitude and longitude, with hover tooltips revealing the specific country and view count. The visualization uses `d3.geoPath` to render land and graticules from World Atlas TopoJSON, while React manages the component state. The dataset is loaded from a CSV file via `d3.csv`, with each point’s radius proportional to its view total.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c431f7fa73b416184936d987483f0cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
