Skip call to selection.merge if undefined. #350

Closed jmcarp closed 5 years ago

jmcarp commented 5 years ago

The selection.merge method was added in d3v4. When selection.merge is undefined, as in d3v3, skip the call and use the existing selection.

This should fix https://github.com/dagrejs/dagre-d3/issues/309#issuecomment-450680411; cc @seelmann.
