    Use mousewheel to zoom in/out. Click-and-drag on canvas/edge to pan.
Shorten distance between vertices connected by multple arrows may clarify the arrows.

Input format:
For quiver (with relations):
Quiver( [.. list of vertices ..], [..[src,tar,arr_name]..] ) [ ... list of relations ... ]
"Quiver()" can be omitted.
Relations must be the last array and cannot be 2-dimensional.
Relations in the "QPA Quiver code" has priority over those in "Relation code".
Known Limitation:
- Can only detect finite field of characteristic at most 61
