The aim of this project is to improve data visualization in MNE when working in the Jupyter Notebook. This will be achieved by implementing a package for interactive 3D visualization of human brain activity inside the notebooks. A working alternative to mayavi and PySurfer built on top of ipyvolume and ipywidgets will be developed. Ultimately, I will add ipyvolume as a backend to the MNE package. Export of data visualization to a variety of file formats will be added.
