* "Overview" shows all courses from the subject you search
* "Path by course" shows which courses you can take after the course you search
* You can zoom in/out and drag nodes to change their positions inside the graph
---
* Path mode:
* "Filters": Filter out subjects you want to ignore
* "Layout": Change the layout of nodes in the graph
* Overview mode:
* The mini-map(only available in overview mode) on the left corner shows which courses are JUST after the one you click
