Manim is an animation engine for creating explanatory math videos, originally developed by Grant Sanderson of 3Blue1Brown. The community edition, ManimCE, is a fork of the original project, maintained and developed by the community. ManimCE is recommended for use in personal projects due to its continued development, improved features, and active community-driven maintenance. It allows users to create precise animations programmatically and has been used to create various mathematical animations and videos.
