When I open in yap a DVI file created from the source code at http://www.texample.net/tikz/examples/drawing-graphs/ the display is wildly incorrect. See attached screenshot and dvi file (both in a 7z archive because sf.net seems to allow only single-file attachments). I have no problem further converting that DVI file to a correctly displaying SVG using dvisvgm. So I assume the problem is in yap rather than in the dvi file.
That DVI file also crashes Evince for Windows, for what that's worth. I assume dvilualatex produces some "bleeding edge" dvi files with uncommon features. But dvisvgm has not problems with it.
