[classDef] Suggestion: extend classDef with default shape

Is your feature request related to a problem? Please describe. I’m frustrated when I use a class (for example “:::redis” which gives it a red colour) I need to manually shape each node. Example:

graph TD
  classDef redis fill:#FF0000;
  database1[(database1)]:::redis

Describe the solution you’d like To simplify using a syntax where the classDef also contains the shape

graph TD
  classDef [(redis)] fill:#FF0000;
  database1:::redis

Describe alternatives you’ve considered Copy paste a lot

I have not given this much thought by now, but this could be done by adding a new attribute shape to classDef as well as style which can also be used to apply styles to nodes. But it should use words as a value, not things like shape:[()] but shape:database. What do you think?

Being able to specify shape in classDef would be really helpful – it would allow specifying semantic classes of nodes and styling them separately. This would be very useful when aiming for a consistent “language” across multiple diagrams.
