{"version":"1.0","type":"rich","title":"Menus with React -Aggregation by Country + Dropdowns!","description":"This interactive map visualizes video view counts for Harvardx/MITx online courses in 2013, aggregating data by country. A dropdown menu lets users filter the displayed points by individual course. The visualization uses D3’s `geoPath` with a Mercator projection to render the world map and graticule, while `scaleSqrt` sizes circles representing views. Hovering over a point reveals the country name and view count. Data is loaded from a CSV using D3’s `csv` function, and the interface is built with React state management for the dropdown selection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8641109ae5d41498a4410c4126fbb74?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
