Getting started with Vispy for high-performance interactive data visualizations

Most existing plotting or visualization libraries in Python can display small or medium datasets (that contain no more than a few tens of thousands of points). In the Big Data era, it is sometimes necessary to display larger datasets.

Vispy (http://vispy.org) is a young 2D/3D high-performance visualization library that can display very large datasets. Vispy leverages the computational power of modern Graphics Processing Units (GPUs) through the OpenGL library.

The power of GPUs has been fostered by the video game industry in the last two decades. GPUs are specialized in high-performance, real-time rendering. As such, they are perfectly adapted to interactive scientific ...
