We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Make interactive visualizations default for Jupyter
<!-- ⚠️ If you do not respect this template, your issue will be closed -->
<!-- ⚠️ Make sure to browse the opened and closed issues to confirm this idea does not exist. -->

### What is the expected enhancement?
The interactive visualizations contributed in PR #765 are much better than the static ones, and should be default when the environment is a Jupyter notebook. This is related to Epic #707 for providing better jupyter tools.

Several issues must be solved first:
- These visualizations need internet connection. Can we eliminate that?
- The interface of the static and interactive visualizations are all the same, except for `plot_histogram` vs `iplot_histogram`. These should be made similar for consistency. But the interactive visualization is able to plot multiple histograms in one plot.
- How "heavy" is it to run these interactive visualizations? I hear my laptop fan.
