Is your feature request related to a problem? Please describe.
When I create an inheritance diagram, I have so many parent classes due to Mixins that I can't read it as it is too small. If the direction were to change I would be able to read it.
Describe the solution you'd like
It would be nice if the configuration option for the inheritance diagram would allow the user to pass in a string indicating the direction of the mermaid chart. (e.g. LR, RL, TB, etc.)
Describe alternatives you've considered
The only alternative right now is overriding with templates, but that leads to a lot of duplicate code for no reason.
