## Overview

Manim is a Python engine for creating explanatory math animations. A user writes a Scene, invokes the CLI to select and render it, and receives a video or image output. Scenes compose displayable objects and animations; renderers turn each frame into pixels, while specialized object, text, graphing, and 3D modules provide the main creative capabilities. The graph follows documented and excerpted relationships; unsampled subsystems are included where the README or source index establishes their role, without asserting unverified calls.

Main entry points: [`manim/scene/scene.py`](https://github.com/kritultrathod/manim/blob/main/manim/scene/scene.py) (Scene lifecycle), [`manim/mobject/types/vectorized_mobject.py`](https://github.com/kritultrathod/manim/blob/main/manim/mobject/types/vectorized_mobject.py) (Vector graphics), [`manim/mobject/mobject.py`](https://github.com/kritultrathod/manim/blob/main/manim/mobject/mobject.py) (Object model), [`manim/cli/render/commands.py`](https://github.com/kritultrathod/manim/blob/main/manim/cli/render/commands.py) (Render CLI)
