Dear Karl,

a couple of weeks ago you developed some code to convert a pair of
tables to a graphviz digraph and you wrote a very useful Worg page about
it:

  http://article.gmane.org/gmane.emacs.orgmode/74280
  http://orgmode.org/worg/org-tutorials/org-dot-diagrams.html

I have today had a real need for this so I copied the code and used
it.  Worked like a charm!  Thanks for doing this.

I just wanted to say two things about it:

1. if the typical use case is to use the code with #+call:, it would be
     more helpful to delete the #+header: line in the source code in the
     Worg page.  This header line presumes that the particular tables in
     your first example exist.  Deleting this line means that the code
     can only be used via a #+call statement but I think this is more
     logical.

2. I appended a column to my node table with a description of each
     node.  You've written your code so that it doesn't care if there
     are extra columns.  This is a bonus!  My table not only provides
     the data for the graph but also explains the graph to a reader.

Thanks again,
eric
