A few days ago, I researched mermaid. Functionally, mermaid has more built-in types, but that’s not the main point. What I want to say is that I find the default flowchart theme of mermaid very comfortable to look at, with automatic coloring. Therefore, I am somewhat curious if Graphviz has a simila…

Short answer: no. There are several current requests, but they are not being worked on (at least not publicly) Longer mumble: There are several ways to approach this capability. But most are OS dependant and somewhat fiddly command line specification (your idea): fairly easy w/ Linux (& MACOS?…

Since it is possible to specify the properties of a node-edge graph in the command line, can we directly store these properties in a file, and then simply read from this same file each time to maintain a consistent configuration?

Surprised, it can actually be used this way to generate a dot file using the cpp command. This should mean that it only utilizes the macro definition feature of cpp.

In that case, would it be more reasonable to use a gvpr file as the theme file and apply the theme by running gvpr once?

the cpp includes, conditionals and line statements could also be used As to using gvpr, I can’t find an easy way to make a gvpr-based solution as powerful as *cpp. Also note that there are several stand-alone cpp varients.

I came to Graphviz from Mermaid and similar tools, and was very focused on writing the graph myself, node by node in the text editor. This is still generally useful, but when I want a specific theme, it gets cumbersome. It took me quite long to make the jump to generating graphs from code. Now it f…

Here is another (partial?) solution: [image] gvInclude.gvpr - insert a Graphviz code file into another Graphviz file Announcements gvInclude.gvpr provides the equivalent of the #include feature of the C pre-processor, without needing any non-Graphviz programs (…
