Bug #98426 for GraphViz2: GraphViz2 adds empty labels to all nodes and edges without an explicitly chosen label

GraphViz2 adds empty labels to all nodes and edges without an explicitly chosen label

I'm using graphviz 2.38.0 For every node and edge defined GraphViz2 adds an empty label attribute: [label = ''] This results in an output_file with blank nodes, as long as the label attribute for the nodes is not explicitly set. This behaviour isn't documented and differs from the way graphviz works, since graphviz uses the name of a node a the default label.
