Hi Alessandro,
There are several sites with definitions and illustrations of "bow tie
diagrams", e.g.
http://www.eagle.org/news/pubs/surveyor/dec99/ism.htm
It wouldn't be too hard to put something together in R to do simple ones
with risk factors on the left and events on the right, but I suspect
that the more complex varieties with barriers and recovery actions are
built up box by box using a pointing device with dedicated software like
BowTieXP. Obviously a "presentation" tool.
