Richard Wettel just announced that a new implementation of CodeCity is available on top of the latest Pharo and Moose.
CodeCity is a 3D visualization engineased on a city metaphor, which enables us to depict software systems as cities. If you want to know more about this approach, have a look here: http://www.inf.usi.ch/phd/wettel/codecity.html.
For example, here is a city of ArgoUML 0.34:
To install CodeCity, you need to run this code in a Moose image:
Gofer new smalltalkhubUser: 'RichardWettel' project: 'CodeCity'; configuration; load. (Smalltalk at: #ConfigurationOfCodeCity) loadDevelopment
You can also get the latest successful build from: http://ci.inria.fr/moose/job/codecity/lastSuccessfulBuild/artifact/codecity.zip
The new CodeCity does not provide a configuration UI, but it relies on scripting. A script to obtain a city visualization of a Moose model is shown here:
A good way to get familiar with the scripting API of CodeCity are the examples. You can open CCBuilder in the Playground and you can browse the examples (the "e.g." tab).
While CodeCity was initially aimed at software systems only, there is nothing that stops you to use it now for visualizing any kind of data!
