This uses graphviz to print a .dot file to a png. Boxes are greyed out after they have been covered in the course.
To learn more about the dot format, see this pdf.
To generate the image after modifying the dot file, try this:
- Install graphviz
brew install graphviz
- Run this command to create and open the image:
dot -Tpng:quartz:quartz developerroster.dot -o devroster.png && open devroster.png
