Hello,

I was looking to getting data from a social network represented as a graph,
I finally found GraphViz module which was excellent,
You can see the graph representation I've been able to render so far here : Screenshots (you can click on it to magnify
but be sure no to crash your browser,the image has 6.4MB).
However,some problems regarding the running speeds frighten me (because of problems with
scalability.
I have just rendered a graph with 10000 nodes and 10000 edges(many isolated nodes)
and it took some 2-3 minutes .
But if I use the overlap=>'false' feature which GraphViz comes with it(I also use
radial layout)
Also the biggest problem is that when I run this with a test it will be
about 1000000 nodes with 100000000 edges.
So I am thinking if this would be feasible and also I can't find any good benchmarks on this
GraphViz module,does someone know any benchmarks of it anywhere ?
An implementation using ajax would also be possible I think...but I don't know javascript
very well.


Regards,
Stefan

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
