Idea: visualization patterns

Each design pattern could come with 'visualisation patterns'. Some kind of analog of style sheets that provide hints on the best way to show term graphs.

As a guiding example consider the lattice:

A generic improvement would be to unfold one or more steps and show graphs for each class expression. See this repo for examples: https://github.com/cmungall/multi-axial-ontology-test

But different DPs could have specific guidance or code. For example, for a transport DP, we can imagine cell maps with an arrow connecting source to target, with the edge labeled with the cargo.

From a discussion with @ValWood and @kltm

No implementation files or tests are named. Start by reviewing the lattice example at QuickGO and the multi-axial-ontology-test repository, then clarify the scope and format of visualization guidance for design patterns. Done requires an agreed specification and an implemented, usable approach for showing class-expression graphs and pattern-specific visual guidance.
