I asked this question concerning tools to visualize and analyse graphs.

Following the suggestion of Dmitry Kachaev, I would be interesting to discuss if this kind of question is on-topic.

Despite of visualization tools are more related to data in general, open data is a particular case of data and sometimes it is necessary to visualize it, so why not?

From my perspective, anything related to Open Data is on-topic, that includes seek, process, visualize, legal/license concernings, etc.

  • Echoing Patrick Hoefler's answer, I would recommend changing the question to use 'chart' rather than 'graph', or otherwise clarifying that you'er talking about data visualization and not graph theory. Commented May 10, 2013 at 20:42
  • I think the question isn't ambiguous about that. The question has nothing to do with graphs but a recommendation of a graph visualization tool (that obviously is going to draw graphs as diagrams)

  • the word 'graph' is ambiguous. The word 'chart' is not. I'm merely talking about changing the headline question which a person would see in a list view, where the detail of the question is not available to clarify the intention. Commented May 11, 2013 at 15:48
  • @JoeGermuska I don't see any ambiguity in the question, but fell free to improve it ;)

  • I'm sorry, I misread the question. Nevertheless, if the edit button weren't disabled for this question, I'd simply change it to 'Are graph viz/analysis tools on topic here?' Commented May 13, 2013 at 16:28
  • @JoeGermuska ah... lol! We were talking about different question, I was thinking in the original question, not this meta-question.

Graphs and graph tools are absolutely on topic for the Open Data SE, since graph structures are becoming an important way to represent data in a interconnected world.

Quick note though: "Graph" in this context means the mathematical graphs with nodes and edges, not charts or diagrams. This could really lead to confusion, especially with regard to tagging. My proposal would be to use or for graph structures and , or for graphs in the sense of charts or diagrams.

  • The usual way to visualize graphs is with diagrams, actually when one is creating a graph it is usually with a diagram representation

  • @RSFalcon7, you're absolutely right. What I meant to say is that people sometimes use "graph" to refer to charts or diagrams, and this is where things start to get confusing ;) Commented May 9, 2013 at 9:36
  • maybe the tag [node-edge-graph] should be used instead of [graph]. I know it's stupid and mathematicians won't like it, but it prevents misunderstanding! The tag wiki should be filled in of course, but I think the tag name should be unambigous by itself, as many people won't read the wiki.

This question might fit better at http://softwarerecs.stackexchange.com

But be sure to include more detailed requirements, for instance:

  • the format of your data
  • whether you want an off-the-shelf tool or a library
  • what is your budget

We can't help you efficiently if we don't know your requirements.
