Re: [jgrapht-users] feature request/help: save (huge) graph to image file

[Joris K. <de...@gm...>]

I'm not behind my computer so it's hard to check any solutions, but here is
something you could do:
export the graph using the DOT exporter. Pretty much any graphical graph
package can read the DOT format. Additionally, I believe there is a CSV
format in one of the pull requests in case DOT isn't supported by the
package. Visualizing large graphs is a very hard, dedicated, research area
on its own.

Btw, the new versions of JGraphT also support exporting to PDF.

I wasn't able to look at your stackoverflow post at the moment, but think
about *how* you want to visualize your graph. If you have >100 vertices,
what would be a good visualization such that the resulting graph is
actually informative? For very large graphs, it is usually better to give
specific statistics about the graph, e.g. degree of connectivity, diameter,
special structures such as planar, etc.
