Compared to ipython, we are currently missing:

• display_markdown -> that's interesting because pander, which displays mostly every thing in R in markdown
• display_jpeg -> to complement the *_png and *_svg one?
• display_latex -> also lots of stuff in R which can transform to a latex representation
• display_json -> that's the one I want -> More specifcations for raw data publications needed? jupyter/jupyter_client#6 (comment) :-)
• display_pdf -> nice for plotting, which should be included in latex/pdf
• display_javascript -> in python used to implement magics, which influences the behaviour of the notebook... Not sure if we need that...
