Drawing a Web Graph

Question

I'm trying to draw a graph on an ASP webpage. I'm hoping an API can be helpful, but so far I have not been able to find one.

The graph contains labeled nodes and unlabeled directional edges. The ideal output would be something like this.

Anybody know of anything pre-built than can help?

Answer 1

I am not sure about ASP interface, but you may want to check out graphviz.

Answer 2

You might be able to pull this off with Google's Chart API. It is very easy to get started with.

Answer 3

I would recommend zedgraph

Answer 4

Definitely graphviz. The image on the wikipedia link you are pointing at was made in graphviz. From its description page the graph description file looked like this:

graph untitled {
    graph[bgcolor="transparent"];
    node [fontname="Bitstream Vera Sans", fontsize="22.00", shape=circle, style="bold,filled" fillcolor=white];
    edge [style=bold];
    1;2;3;4;5;6;
    6 -- 4 -- 5 -- 1 -- 2 -- 3 -- 4;
    2 -- 5;
}

If that code were saved into a file input.dot, the command they would have used to actually generate the graph would probably have been:

neato -Tsvg input.dot > graph.svg

Answer 5

GraphViz does a nice job for tiny graphs, but not for huge ones. If your graph is reasonlably large, try aiSee or have a look at the alternatives on this list.

Answer 6

You could use QuickGraph to easily model the graph programatically, then export it to GraphViz or GLEE, then render it to PNG.

Answer 7

Well, here's another answer 2 years later. Protovis now does force-directed graph layouts rendered in browser: http://vis.stanford.edu/protovis/ex/force.html Might be easier if you can't install client-side software. Also it's fun and interactive!
