About matplotlib.online

matplotlib.online is a web-based tool for creating high-quality plots using Python's matplotlib library. It is designed to be easy to use and accessible to everyone.

The data processing and plot rendering is done entirely in the browser using Pyodide, a Python interpreter compiled to WebAssembly. This means that you can create plots without having to install any software on your computer, and it can even work without internet access thanks to localStorage.

Alternatives like Google Colab and Jupyter Notebook are great tools for data analysis, but are tedious to use when creating plots, especially when making small incremental changes to the plot and see the result immediately. Additionally, they are relatively slow to run for simple plots, have an awful code editor, and require an internet connection.
