This is because of what seems to be a bug in babel -- :colnames
options are not being respected in/for call lines. You always get the
above error when trying to process a table in elisp and the header is
not removed.

The solution is to specify the range on the call:

#+call: 
graph-from-table(nodes=example-node-table[2:-1],graph=example-graph[2:-1])

You will also need to specify results :file; and the filename as a
parameter to the called block not the call. `Call's always export the
results i believe (you can add :exports results to the orginal source 
block).

#+call: graph-from-file[:file out.png](...) :results file

I don't think there is a :resname option. There was a #+RESNAME:
keyword, but it has been replaced w/ #+NAME:, which is currently not
functional for call lines (but is a hot topic in another thread on the
list.)
