I would like to try out the diagram-viewer app and the diagram pkg.

As you can see, diagram-viewer can't find the diagram package even
though it is there.
 
Nor can I find any other examples of the diagram language nor what file
extension one should use.

Sorry, keep forgetting that the Pan newsreader's editor eats (selected)
newlines:

The file /tmp/a.dia is (with no blank lines):

box A

arrow "" 40

circle B

direction SE

And the console interaction (again with no blank lines):

$ wish9 ~/opt/tcl9/bin/diagram-viewer show /tmp/a.dia

Creating safe environment, please wait...

/home/mark/opt/tcl9/bin/diagram-viewer: can't find package diagram

$ wish9

% package require diagram
