Hello, I'm new to Mondiran and I'm trying to run very simple piece of code:

| view namespaces |
namespaces := MooseModel root allModels first allModelNamespaces.
view := MOViewRenderer new.
view shape rectangle
  width: #numberOfClasses;
  height: #numberOfMethods;
  linearFillColor: #numberOfLinesOfCode within: namespaces.
view nodes: namespaces.
view edgesToAll: #providerNamespaces.
view dominanceTreeLayout.
view open.

I tried with Roassal Easel but it doesn't compile. Where should I put the code and run?
