PDFLaTeX: nodes and edges with hyperlinks?

How to set up the system such that hyperlinks are attributed to nodes and elements in graph contained in a .pdf produced by a LaTeX?

Here what I know so far:
- href/URL tag in .dot file is ignored when converted to .pdf by dot (http://www.graphviz.org/doc/info/attrs.html#d:URL)
- .dot included in .tex doc is converted through .pdf by dot2tex (http://www.ctan.org/tex-archive/graphics/dot2tex)
- .eps/.svg included in .tex doc are channelled through .pdf by pdflatex, too

Any input highly appreciated.

I can't recall how to keep

I can't recall how to keep the links whence going from latex + includegraphics to pdf, but for the first step, you can't use -Tpdf. This relies on pangocairo to produce pdf and that software doesn't preserve links. (We've asked for the feature for years.) See

CTAN package: epstopdf

Great. This is very helpful. While I couldn't find the mentioned epsf2dpf, the perl script epstopdf (http://www.ctan.org/pkg/epstopdf) does the trick. Many thanks - for graphviz as well. -J.

Great. This is helpful. While I did not find epsf2pdf in the net, I tried epstopdf (http://www.ctan.org/pkg/epstopdf) which did the job in a small example.

Many thanks again - and for graphviz as well, of course!
