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.
