By virtue of being a pure Python library, molli can be easily interfaced with a few different visualization libraries. Molli uses two different engines for visualization purposes, the first is 3DMol.js, which is used for simpler molecular renderings inside Jupyter notebooks. This implementation allows a very simple, in-place visualization that helps the end user understand the contents of their molecular or conformer libraries much better without the need to transfer the data to a third-party program for rendering.
