Note: This is a temporary test environment in which you can play around with Manim without the need of installing it locally. Keep in mind that this is a temporary environment, though: your changes will not be saved and cannot be shared with others. To save your work, you will need to download the notebook file ("File > Download as > Notebook (.ipynb)"). Enjoy!
