• Pyface: toolkit-independent GUI abstraction layer, which is used to support the "visualization" features of the Traits package.
• MayaVi: 2-D/3-D scientific data visualization, usable in TraitsUIs as well as an Envisage plug-in.
• Envisage: An extensible plug-in architecture for scientific applications, inspired by Eclipse and NetBeans in the Java world.
• Enable: A multi-platform DisplayPDF drawing engine that supports multiple output backends, including Windows, GTK+, and macOS native windowing systems, a variety of raster image formats, PDF, and PostScript.
• BlockCanvas: Visual environment for creating simulation experiments, where function and data are separated using CodeTools.
• GraphCanvas: library for interacting with visualizations of complex graphs.
• SciMath: Convenience libraries for math, interpolation, and units
• Chaco: An interactive 2-D plotting toolkit for Python.
• AppTools: General tools for ETS application development: scripting, logging, preferences, ...
• Enaml: Library for creating professional quality user interfaces combining a domain specific declarative language with a constraints based layout.
