Note: a special case arises when graph $G$ contains selfloops. Selfloops (as well as multiple edges) simply add additional nodes to line graph $L(G)$. When $G$ is directed, a selfloop $e=(v,v)$ in $G$ results in a vertex $e$ in $L(G)$, and in addition a selfloop $(e,e)$ in $L(G)$, since, by definition, the head of $e$ in $G$ is incident to its own tail. When $G$ is undirected, a selfloop $e=(v,v)$ in $G$ results in a vertex $e$ in $L(G)$, but no selfloop $(e,e)$ is added to $L(G)$, since, by convention, the line graph of an undirected graph is commonly assumed to be a simple graph.
