Edge label

All kinds of labels

label	xlabel	headlabel	taillabel

Difference between label and xlabel 1

Attribute label works not good as expected while using in subgraph.

label	xlabel	label in subgraph	xlabel in subgraph

Difference between label and xlabel 2 (constraint=false)

• The label is gone.
• Space of xlabel is not enough.
