## Overview

This is a single-file Tkinter graphing calculator. The principal workflow is entering equations, plotting them on a Cartesian canvas, and adjusting zoom or line colours; separate menus provide symbolic differentiation/integration and display settings. The sampled source confirms plotting and SymPy calculus calls, while language, fullscreen, and theme capabilities are documented in the README. Because the application is monolithic and excerpts are incomplete, the graph uses the same exact source path for its logical components and omits uncertain internal wiring.

Main entry points: [`graphing_calculator.py`](https://github.com/idris-p/graphing-calculator/blob/main/graphing_calculator.py) (Tkinter interface)
