Graphics, Figures & Tables ⇒ Advice on building dependency diagram

[nvedia]

I have to build a dependency diagram

There are 5 systems, S1, S2, S3, S4, S5

S1 --> S2 means S1 depends on S2

S1 --> S2, S3, S4

S2 --> S3, S5

S3 --> S2, S5

S4 --> S5

S5 --> S1, S2, S3, S4

How can I build dependency diagram like the one attached?

Also, is it possible that once I click on node S1, I get all the direct dependencies highlighted?

Hi and welcome,

for drawing, i would recommend tikz. A bunch of quite similar graphs can be found in the graphs directory of TeXample.net.

What exactly do you mean by clicking and highlighting? Not sure, if this is so easy without the normal pdf-spec.

Thanks Johannes_B
This is what I mean by highlighting

Also, using Texample, can I just put my dependencies in one file and all the graphs would be built automatically as I keep changing the data ?

[Johannes_B]

the pdf format is kind of static, for good reasons. There might be something doable with Java Script inside pdf, but this is not really a good idea (imho).

What do you mean by putting all dependencies in a file? Each graph will most likely be on tikz-picture. You need to do manual some work to get the graphs, there is no completely automated version.

What I mean is given this data
S1-->S2, S3
S3-->S1, S4

the program should position the nodes and draws lines accordingly between different nodes

Ah, now i understand. Yues, tikz should do that for you.
But to be honest, i am no tikz expert.

[Stefan Kottwitz]

Yes, there's a graphdrawing library which works on similar dependency input, and creates graphs. It's described in the TikZ manual, Part IV. I just don't have a compiler at hand right now, perhaps I can show an example later.

Here's a sample with your data.

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,graphs,graphdrawing}
\usegdlibrary{trees, layered, circular, force}
\begin{document}
\begin{tikzpicture}[>=stealth, rounded corners]
  \graph [layered layout, level distance=6em,
    sibling distance=8em,
    nodes={draw,circle}] {
      S2 -> {S3, S5},
      S1 -> {S2, S3, S4},
      S3 -> {S2, S5},
      S4 -> S5,
      S5 -> {S1, S2, S3, S4};
      { [same layer] S1, S4 };
      { [same layer] S2, S3 };
    };
\end{tikzpicture}
\end{document}

Compiling with LuaLaTeX gives:
