Incorrect edge rendering with latest graphviz

[jesperolsson-se]

The edges between tables are not rendered correctly using graphviz 9.0.0. The arrowtails are rendered, but the rest of the edge is cut off or missing completely.

Expected Behavior

The complete arrows should be rendered.
Alternatively, SchemaSpy/Graphviz version compatability should be documented clearly.

Current Behavior

SchemaSpy produces valid .dot but at incorrect .png, .svg and maybe more image formats.

Possible Solution

This might be a bug or breaking change in graphviz.

Steps to Reproduce (for bugs)

1. Install Graphviz 9.0.0
2. Run a valid SchemaSpy command.

Context

Your Environment

• Version used: 6.2.4
• Operating System and version (e.g. Windows 10): Windows 10

@jesperolsson-se have you tried with more versions if Graphviz.

Is this an issue with Graphviz or a SchemaSpy issue?

@npetzall
The last graphviz version before 9.0.0 was 8.1.0, which displays the correct behaviour.

SchemaSpy produces the same .dot file, and running e.g., dot example.dot -Tpng -o example.png results in the same unexpected behaviour. However, I don't know if its an intentional breaking change on their part or not. I've opened an issue in the Graphviz repo, so let's see how they respond.
