FreeOrion

My brain isn't as good as it was 20 years ago. I need some tool to contain and visualise all the tech tree info and also allow online collaboration.

It should:
1. Work on Linux, Windows and Mac.
2. Allow easy (fast) edition.
3. Produce nice and clear flowcharts.
4. Allow online sharing and collaboration.
5. Be free and opensource.

Ideally, it would:
6. Allow automatic organisation based on characteristics (cathegories) of the items.

I'm testing (right now) http://diagramo.com/
It is browser based (HTML5) and it seems to meet requirements 1 to 5, but it seems it does not have functionality 6.

Do you know of a better alternative, or is there anything (better or not) already in use by FreeOrion developers?

Thanks in advance.

PS: @labgnome? Maybe you have already not only a good app for this but also most/all of the work done.

Looking at diagramo it looks like the positioning is free floating.

I guess something which provides lanes and allows to drag and drop of nodes inside the existing tree would be more efficient. Dont know such a tool though.

Try mermaid. it is similar to graphviz, as it uses text to describe a graph. The online editor runs on any recent browser with enabled JavaScript. Other implementations exist to run mermaid from commandline Sharing documents is as easy as sharing the link to the editor (the editor link above is in fact a recreation of the first graph in that post by me).

That's is just great! The text-to-graph functionality is very welcome (didn't mention it on the OP). Appreciate it!
