Dropdown attempts - EdX Viewing Patterns by Country, 2013
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.
AI-generated descriptionThis is a visualization of the Harvardx/MITx Course-Person Dataset for the academic year 2013. The data shows the number of video views of the online courses, represented by the circles on the map. The data can be found here.

The world map behind the points is a Mercator type map using the World Atlas TopoJSON. The points are off by a small fraction (down and to the left) however it fits much better on the Mercator projection over the Natural Earth projection. When the user hovers over each point, they can see the latitude and logitude of that deployment.

Trying to add a dropdown menu here, by course.
