Jupyter(-hub) expects the worksheet to be self-contained, so the entire graphics data needs to be embedded without any further calls to the backend. Thats the only way that you can then share the notebook on nbviewer or github, say, and graphics still works. Jmol's architecture is fundamentally

Unfortunately, I have not got time to dig through the code and understand what needs to be done to pass data properly to jupyter hub. It appears that paths need to be specified using a particular utility function. That part may be easy, but it is not clear to me where everything needs to be adj

Hi, A related note: there is ongoing work at https://trac.sagemath.org/ticket/12402 to use three.js for 3d graphics in Sage, especially in Jupyter notebook. It is almost ready and has already features far superior to jsmol (e.g. axes labels). Hopefully, it could be merged in Sage 7.5. Then, we
