You can make the rows be of size 0:
--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC dot :file test2.svg :cmdline -Kdot -Tsvg
graph foo {
row1--row2--row3--row4 [style="invis", fixedsize="true", width="0", height="0"];
row1, row2, row3, row4 [style="invis", fixedsize="true", width="0", height="0"];
...
--8<---------------cut here---------------end--------------->8---
