%global _description %{expand:
VisPy is a high-performance interactive 2D/3D data visualization
library. VisPy leverages the computational power of modern Graphics
Processing Units (GPUs) through the OpenGL library to display very
large datasets. Applications of VisPy include:

- High-quality interactive scientific plots with millions of points
- Direct visualization of real-time data
- Fast interactive visualization of 3D models (meshes, volume rendering)
- OpenGL visualization demos
- Scientific GUIs with fast, scalable visualization widgets (Qt or
  IPython notebook with WebGL)}
