Built with React and D3 v5, it uses d3.geoMercator and d3.geoPath to render world map boundaries from World Atlas Topojson, while data points are positioned by longitude and latitude. Hovering over a circle reveals the aggregated view count and country name.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bca569fb919439a8f9f5db2fc33cce7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
