# Learning Observable Plot via Altair Between 2018 and 2020 I was actively involved with the Altair community, creating many examples for the documentation and gallery. It was the first time I had used a visualization library inspired by a layered grammar of graphics and it was an eye-opening experience. Learning to use Altair, and understanding the Vega/Vega-Lite projects it is built on, completely changed the way I think about visualization and the creation process. I even made a few YouTube videos on the subject. When Observable Plot was released in May 2021 I was impressed with the beautiful visualizations being created and wanted to make some of my own. Unfortunately, I didn't have the time back then to dive in and learn, but now I do! ### Disclaimers The purpose of this notebook is selfish in nature; I am trying to learn Observable Plot. It is very similar in spirit to the piece Plot & Vega-Lite by Ian Johnson, which I recommend. This notebook is not meant to be a tutorial or explainer, but I wanted to share anyways. My goal here is to take some of the examples from the Altair Example Gallery and recreate them using Observable Plot, as a means of learning. I've decided to include many of the errors and difficulties experienced during the creation process, rather than only keep the final result. I think that sometimes it's important to see the false starts and misunderstandings as they can be informative. I hope you enjoy! 😀
