On 12/3/21 I had a call with Jeff Heil of Belearning. He shared his new software project, Cauzality. See more here.

Marc and I reconnected with Jeff last week (early Sep 2023). They have developed it a lot but there are still things missing like driver tress, network/matrix representation and SVG export.
Jeff is going to see what they can do. At least about SVG export.
