Prerequisite chart

Example of a prerequisite chart made with the PGF/TikZ-based prerex package. Real examples can be found at the Queen's University School of Computing.

The prerex package includes the source code for an interactive editor of prerex charts and patches to kpdf/okular to enable grabbing coordinates directly from a chart display.

Edit and compile if you like:
