Create a python library for making beautiful mathematical animations like the ones in 3 blue 1 brown videos. Let users write simple scripts where they define a scene by creating shapes such as squares, circles or text then tell it what to do like draw the square, rotate it, transform the square into a pink circle and fade everything out at the end.

Running a command on the script should output a smooth video file that can play automatically. Keep the api really clean so someone can start with from manim import star, inherit from Scene and put everything in a construct method with self dot play calls for the animations. Make it versatile enough for explanatory math videos yet easy to install and run on a laptop. If you need to check current best practices for video rendering or math plotting feel free to look those up.
