The vertices (nodes) are bus stops in a small town. The vertices table lists each bus stop and the boarding fare at that stop.

The edges table represents the bus route. The columns nodeid and nodestring identify the source vertices (where the bus starts) and the columns endnodeid and endnodestring identify the target vertices (where the bus stops).
