Research direction

Examine the edge label rendering code in the Diagrams library, likely in graphviz related modules. Investigate how label positioning attributes are set and compare with working examples. Look for existing tests or comments that might explain the behavior. Consider if the issue is due to graphviz version or attribute conflicts.
