Display note title in Graph view instead of filename

I am using Obsidian v0.11.9. In Graph View, the file names of my notes are displayed. I follow the convention of naming a note with words separated by “-” (Eg graph-view.md) and will have the first heading (H1) as “Graph View”.

Is there a way I can show the note title instead of the note file name in graph view?

No - not yet at least. There is a feature request which, once implemented (and there might be a good chance for implementation sooner or later…), will probably apply to the graph view as well.
