Long captions in graph nodes

[opudrovs]

Long captions go beyond graph node boundaries:

Possible solutions:

• Add wrapping to text in graph nodes (and make nodes taller). The text has no spaces, maybe it should be broken on a dot instead?
• Nodes could be wider, but it will lead to too nodes being to wide for shorter text. Maybe we could check the text length, and if it is longer than a cutoff, should use a bigger node for this text without affecting other nodes?

Acceptance Criteria

• We will truncate name by ... using overflow.
• As a user when I hover over the node, I will see the full name as a tooltip.
