Abstraction: Pure-Python Qt-based library for real-time scientific visualization

Key points:

Primary advantage over matplotlib: speed for rapid plot updates, video, and realtime interactive graphics
Pure-Python, no compilation required; runs anywhere numpy and PyQt are supported
Provides advanced science/engineering features: ImageView, ScatterPlotWidget, ROI-based data slicing, parameter trees, flowcharts, multiprocessing support
Compared unfavorably to matplotlib for static publication-quality graphics (matplotlib recommended for new projects without realtime needs)
VisPy (collaboration of PyQtGraph, VisVis, Galry, Glumpy authors) aims to replace Qt with OpenGL as a rendering backend
PyQwt (predecessor) is unmaintained; its maintainer recommends migrating to PyQtGraph
