{"version":"1.0","type":"rich","title":"Jim's Help - EdX Viewing Patterns by Country, 2013","description":"This map visualizes global video viewing patterns for HarvardX/MITx online courses in 2013, with circle size representing the total number of views per country. A dropdown menu filters the displayed data, though filtering by country is not yet wired to the visualization itself. The view combines a Mercator projection rendered via `d3.geoPath` from World Atlas TopoJSON with circle marks, using `d3.scaleSqrt` for radius encoding. Data comes from the HarvardX/MITx Course-Person Dataset, loaded with `d3.csv`, while the interface is built with React and the `react-dropdown` component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a981b67f19f1405c94cf1cec735439ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
