NAME
Graph::MoreUtils::Line::SelfLoopVertex - marker for artificial self-loops
DESCRIPTION
With loop_end_vertices
option Graph::Line adds self-loops on pendant vertices thus preserving them from getting "lost". Instances of Graph::MoreUtils::Line::SelfLoopVertex are used to represent the artificial self-loops in the resulting line graphs.
