Great call and initiative. I would like see - better arrows (this is related also to the third point) - get the graphViz algo finished (even if not fully working) Anne and guillaume got lost in translation there but it would be a real game changer. - having a better output (arrows, edge) and animation (like the web library Telescope is using to render visualisation on the web) Guillaume knows it name. (Guillaume what is the name of the library you use) Stef Le 24/2/16 09:51, Alexandre Bergel a Ã©crit : > Dear community, > > As you may have seen, Roassal has entered a stabilization phase.
