[Jprogramming] graphviz: missing graphview_darwin.ijs ? do I need separate graphviz executable?

[Murray Eisenberg]

I’m running  j64-807 under macOS.

(1) I manually installed the graphviz addon, into ~addons/graphics/graphviz. 

In j64-807, following the docs I executed:

	load '~addons/graphics/graphviz/graphview.ijs'

This causes error…

	not found: /applications/j64-807/addons/graphics/graphviz/graphview_darwin.ijs

… which is no surprise because the script graphiview.ijs consists in its entirety of:

	NB. graphviz - main interface file
	require 'graphics/graphviz/graphview_',(tolower UNAME)

And in fact there is no such script graphview_darwin.ijs included in the downloaded graphiviz.

(2) At https://code.jsoftware.com/wiki/Addons/graphics/graphviz <https://code.jsoftware.com/wiki/Addons/graphics/graphviz>,
it says — and this is for J503a ! — that "Mac OS X it requires installing http://www.pixelglow.com/graphviz <http://www.pixelglow.com/graphviz>”.

But the target of that latter link is for graphviz 2.20.3, and on the download page at pixelglow, the link to graphviz-2.20.3.pkg is broken.

Do I still need this quite old (2004) package to use graphviz under J? If so, how get it?

Or do I need instead the executable graphviz obtainable via MacPorts?
