I too would like to see a Jupyter implementation of X3D. It has already been shown possible with X3DOM document as a string, see this for inspiration: https://qiita.com/tenfu2tea/items/024d89564b9b316477ac
This may be useful for using Cython with Jupyter:

Appreciate your asking, Holger.
As you can see from the mail list, there is still a lot of "hammer and tongs" banging going on. We expect to continue refining the Python API syntax, and look forward to potential additional refinements when we look at Masaki Aono's code patterns with Myeong Won Lee.
Meanwhile the existing initial "X3DPSAIL" build has a lot of pieces/parts, closely tied to Java and X3DJSAIL "full" .jar as underlying engine. Python installation and configuration was quite tricky, for me at least. The X3DJSAIL build currently takes multiple libraries to create, which is difficult and complex to set up... but using X3DJSAIL .jar sidesteps all that.
Things are steadily improving. The Java code examples can now be tested as a whole for each X3D Examples archive, or for individual scenes. Testing of the Python examples at least occurs in the large; more improvements expected, including singleton conversion/compilation/execution of X3D python models. Round-trip testing means we have recently achieved spiral improvement stage, which is a big accelerator guaranteeing steady forward momentum. Our next new "hill to climb" in June will be attempting creation of a Python PIP module to further simplify use. We shall see... this is a marathon, not a sprint.
Hoping that continuing progress on this big plan gets us to the point where programmers such as yourself can try things out starting this summer. The Python work is fully public and under version control. Direct feedback always helps and is always welcome.
Looking even further ahead at standardization:
a. Planned end date for accepting X3Dv4 functionality proposal (e.g. nodes, components) is 16 DEC 2019.
b. X3D Working Group will finalize document editing and confirm multiple implementations during January~March 2020 before recommending adoption.
c. Subject to Web3D Consortium member approval of X3Dv4, Web3D draft publication and formal ISO submission immediately follows.
d. Corresponding document editing, updates and submissions for each of the 19776 language bindings and 19777 file encodings then proceed next, upgrading each to X3Dv4.
e. The consistency of the X3D Unified Object Model (X3DUOM) and autogeneration of multiple code sets facilities multiple implementations and 100% consistency.

Again thanks for asking. Having fun with X3D Python! 8)

>> Steady progress on Python SAI using Java-based X3DJSAIL by John Carlson and Don Brutzman, having a test framework for all examples is helping a lot. Working on a Python PIP install next. Korea Chapter has also indicated that an independent Python encoding is emerging, comparisons expected soon, hopefully based on C implementation since we might then use Cython for native implementation in Python language itself. Exciting.
