NACRO Membership by Institution
This map shows the geographic distribution of NACRO (National Association of Collegiate Research Administrators) membership across US institutions, with circle size encoding the number of members per school. Built with Vega-Lite and D3.js, it layers institution points over a US state map using the Albers projection. Data comes from the NACRO Member Geography dataset, which was joined with geographic coordinates from the College Scorecard Dataset. The visualization uses `vl.markCircle` for the points and `vl.markGeoshape` for the state boundaries, with tooltips revealing institution names.

The map shows where NACRO members are located, and which institutions have more (or fewer) members. NACRO would like to enable members to connect with each other, formally through regional groups, and informally. Eventually, I'd like to make the map interactive to show member contact information when you click on an institution, and maybe also to generate a list of members by region. I'm happy to have connected NACRO institution names with geographic coordinates, so that I can now pull in other NACRO survey results and show them geographically. At a more minor level, for this map, it would be good to show both the institution name and the number of members on the tooltip, but I couldn't figure out how to make two variables show up. I forked this from another student's map, credit where credit is due.
