{"version":"1.0","type":"rich","title":"Aggregation by Country using Map","description":"This example visualizes the geographic distribution of video views for Harvardx and MITx online courses in 2013. Circles positioned using a Mercator projection show total views per location, with a tooltip revealing the country name and view count. The visualization combines React for component rendering with D3’s `geoMercator`, `geoPath`, and `scaleSqrt` for sizing. It overlays aggregated view data from a CSV dataset onto land and graticule shapes generated from TopoJSON world atlas data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/344a6eeb501f4be69a738a68e95d3971?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
