In Jupyter it is convenient to dump JS library code to the notebook when "using Module" is run. This is simple to do in the Module's __init__(), and saves a ton of memory since later visualizations can share this common JS library code.
However, if a user re-executes the cell, the library code is gone, because __init__() is not re-run and the output is overwritten. (this will effect the page next time it is reloaded) *Where can I put code that will be run every time "using Module" is executed, and not just the first time?* Thanks!
