MCAS graphing experiment

This graph represents MCAS results for grade 10.

The Massachusetts state boundary lines are from the U.S. Census Bureau. MCAS data from Massachusetts Department of Elementary and Secondary Education. I gathered geometry data for schools by running each school name through the Google Maps Geocoding API and checking each result as best I could.

I used the d3.js Javascript library for SVG rendering and data manipulation.

The source — mostly some poorly-named scripts to download, parse, get geography, and aggregate data, along with Coffeescript to do the drawing — is available on Github if you’re interested (but it is not well organized!)
