Preview onto version 0.3.4
Here you can do some experiments with Rascal. The computation time is
restricted to about 10 secs to prevent high load on server.
Have a look at the documentation or at the examples. If you see wrong plots reload may help.
You job is cancelled as soon someone else accesses this page, so consider a
local installation.
