Description

This is currently supported for the Compose.jl and TikZ diagrams, but not yet for the Graphviz diagrams, except at the global level. It should be possible to assign specific boxes their own styles, via Graphviz node and cell attributes.

Research direction
Investigate how box specific attributes are implemented for Compose.jl and TikZ diagrams in the Catlab.jl repository. Identify the relevant source files for Graphviz wiring diagram rendering (likely in src/ directory). Then extend the Graphviz diagram generation to support per box attributes by modifying node and cell attribute assignments.
