# Graph::MoreUtils::Line::SelfLoopVertex(3pm)

marker for artificial self-loops

## 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.
