Alignment of text labels

[hadley]

I think they should be either below, or to the right, but putting them on the bottom-right corner looks a bit weird.

I like right.

Problems generally occur with nodes in the middle or left side as the arrow lines will be coming from the right side of the node. I couldn't find an acceptable solution by having the labels on the right.

Putting them on the bottom will increase the height per node, but it's not the worst.
