Quicksilver is a tool for interactive exploration of large data sets with the help of hierarchical graphs.

The following is an image generated with Quicksilver: it represents knowledge flow in StackOverflow in the first 5 years of its existence. For more details see the paper published at SSE’13.



To load and play with Quicksilver run the following code in Pharo:

Gofer new
        smalltalkhubUser: 'Quicksilver' project: 'Quicksilver';
        package: 'ConfigurationOfQuicksilver';
ConfigurationOfQuicksilver loadDefault.


To see Quicksilver in action try these examples:

QsFilesystemViewer for: '/some/path/on/your/system'

This will open a tree map view of a directory, with files and folders not modified for a long time highlighted darker

QsSystemViewer for: 'Zinc'

This will open a view of the system with given name, in this case all packages starting with the name ’Zinc’.

These and more examples can be found in the Quicksilver-Examples Packages

Hierarchical Graphs

At the core of Quicksilver we use hierarchical graphs to conquer the complexity of large data sets.

You can look at the documentation of the hierarchical graph algorithms here.

At PharoConf & MooseDay 2013 in Bern, a small presentation about hierarchical graphs and Quicksilver was given.



As part of the development of Quicksilver, we implemented and contributed a tree map layout to Roassal.

Check out the documentation for the TreeMaplayout here.
