I have a graph file to draw using "dot". I don't want to show any label for any node. I am wondering how to do this without specifying a configuration for each node since there are too many nodes in the graph.
Try inserting the following line before all node declarations:
node[label=""];
Of course, nodes which have their label property defined will still have their label displayed.
Also, if I remember correctly, at least one node shapes does not use the label:
node[shape=point]
