Bug Description

When I try to export a graph with several thousand nodes to PDF or SVG, but no edges I get a "java.lang.NullPointerException". The resultant exported file cannot be opened because it is "damaged".

Hi, could you share the dataset so that we can reproduce the bug?

Here is a set of data that causes the NPE. Open the GDF, and then try to export it.

This issue happens because by default, a DHNS instance isn't a directed graph, neither an undirected or mixed graph (by default, DHNS.directed = DHNS.undirected = DHNS.mixed = false). This patch fixes this issue by assuming that a graph that is not directed or undirected, is a mixed graph. I'm not sure if that's the best way to fix this issue, but it does work.

Patch applied in rev 2147, thank you much Luiz!
