For more info on the second utility I tried to present, GraphViz, check
https://graphviz.org/ where are are documents and examples.
The name of this utility probably was coined by and engineer. It is
precisely descriptive, but by itself doesn't tell you why you would use
it. GraphViz produces a diagram that visualizes the graph you provide as
input. These graphs from discrete mathematics and not formula or data
plots. Think more of objects and the connections between them.
You might think of graphs as a superset of mindmaps, but rather than
approaching it from brain-storming, it is documenting existing
relationships. Like for my home network, I could do
- graph of physical connections between systems, switches and routers.
- graph of systems network services primary and secondary providers
You can also use doxygen to generate a state graph from source code.
Check the GraphViz.org site for the domain-specific source file format
(dot), and the various command line tools to generate diagrams. View
https://graphviz.org/docs/outputs/ for a list and diagram of these.
