This example shows how to build a simple 2D aimbot with an ESP overlay (drawing on screen) using ImGui, a library for building UIs in games or apps.
ImGui (short for Immediate Mode GUI) is a lightweight library used to draw things like buttons, text, shapes, and overlays — often used in games, tools, and cheat engines. It's super fast and works by drawing the UI fresh every frame.
