This chapter has provided an overview of a few tools for effectively and interactively exploring data in JupyterLab. We started by going through an overview of extensions and learned how to implement a TOC in a notebook. By now, we know how to install the extension, view the TOC, navigate the TOC, and display extra information in the TOC. Then, we learned to use the commenting extension and understood how to install the extension along with creating, replying to, and resolving comment threads. Finally, we learned how to build interactive widgets to explore data.

In the next chapter, we will learn to share and present our work through JupyterLab's menu options.
