Getting started

Documentation

For viva and vv_treemap, you can get some documentation on the man pages.

  • viva (Interactive Graph Visualization)
  • vv_treemap (Squarified Treemap Visualization)
  • Paje File Format (Complete description of the Paje file format)

External tools, tracers, et cetera

There is a comprehensive list of available tracers/converters that generate Paje trace files. The old Paje website aggregates a bunch of information on the Paje approach, such as publications and so on. If you have traces in Rastro, TAU, OTF2, and OTF trace file formats, keep in mind that there is a converter from each of these formats (using Akypuera tools) to Paje. If you need to create your own Paje trace file generator, we strongly encourage you to use libpoti, since all future evolutions of the Paje file format will be firstly available through poti.
