Summary0001903: Twopi graphs with childless/leaf node at root should not get distorted
Description



Twopi graphs with childless/leaf node at root should not get distorted. The code attached will show that the childless/leaf node at root messes up the distribution in concentric circles, which one does see when that node is removed.



Tru out the code with twopi -Tx11 to see the distortion and compare it to the output when the following line:
<CD>
  TEST -> "7.x.x.x.x.x.x"
</CD>
has been commented out. This effect is not appearing when a second order node is childless/leaf.



Fixing this bug will offer the same kind of quality representation that one expect and does get when this node is removed.
Additional Information

[erg]
Not sure I fully follow this one. The "distortion" is due to the different choice of roots depending on whether or not the
edge
<CD>
  TEST -> "7.x.x.x.x.x.x"
</CD>

is in the graph. If you specify you want TEST as the root in both cases, the layouts are similar.

[pander]
Ah, I didn't know about setting root. This fixes it. Sorry to jump to the conclusion that it was a bug.
