Node connected to itself with default lifestyle looks not great.
(Firstly this library is awesome, so hopefully this doesn't come across as ungracious.)
If a node is connected to itself in a graph with the default linetype, the graph looks weird. However, if linetype=curve, then the graph looks great yet again.
Proposing to default the linetype to curve for an edge which originates and ends with the same node.
@NAThompson thank you for this feedback. This is fixed in PR #186, which will hopefully be reviewed someday and merged.
