The erDiagram gets to to wide and impossible to read

[mrTorb]

Describe the bug
The erDiagram gets to to wide really fast. Especially with many to many relationships with a junction table which seems to build to the side.

To Reproduce
add tables until it gets to wide.
also see mermaid-js/mermaid#2807

Expected behavior
at a certain width it has to break to a new row. It would be neat if I could set a maximum workspace width
Another solution could be to allow for higher zoom ratio

Desktop (please complete the following information):

• windows 10
• vscode 1.79.2
• v0.18.1

Thank you for your report! I think this is caused by the old mermaid version. I published v0.19.1 with the latest mermaid.js. Could you try it?
