{"version":"1.0","type":"rich","title":"Dropdown attempts - EdX Viewing Patterns by Country, 2013","description":"This map visualizes geographic patterns in EdX video views for the 2013 academic year, with circles sized by total views per country on a Mercator projection. The visualization includes a dropdown menu to filter countries, though the filtering logic is incomplete. The React application uses d3.geoPath for map rendering, d3.scaleSqrt for circle sizing, and loads world geography from World Atlas TopoJSON while view data comes from a CSV of Harvardx/MITx course records.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5b1be2e6907141f789b46af64fba74cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
