I am loading graphml files not created using yEd. I spent quite a bit of time trying to figure out a very simple widely-recognized way to add text labels to nodes and edges. I finally stumbled on something that worked if I did Edit > Properties mapper ... and selected and applied single (until today, same file now says <No Value>). Below is what had been working. But is there a simple and conventional way to do simple edits to basic graphml to have labels display on load?
Hmm, no copy-paste or attachments. Here is the basic idea:
<key id="nodeLabel" for="node" attr.name="nodeLabel" attr.type="string"/>
<node id="foo"><data key="nodeLabel">myLabel</data></node>
