Jim's Help - EdX Viewing Patterns by Country, 2013
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.
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.
