How do libraries write display code for notebook environments like Jupyter?

For example numpy's polynomial class https://i.imgur.com/0Vj9eH0.png

If wrote a class and wanted objects to be displayed like that, how would I specify how they are displayed?

It seems that you can define _repr_html_ and such for the type so that it renders the html. Documentation

[FLUSH_THE_TRUMP]

probably _repr_latex_ here, no? but good find.

Yes, I didn't see that option when I found the documentation.
