## Description

Easy Pie Chart is a lightweight JavaScript library designed for rendering animated, circular progress indicators. It functions as a front-end component that visualizes single-value numerical data as responsive pie charts, allowing for the representation of percentage-based information within web interfaces.

The library utilizes HTML5 canvas elements to draw graphics, leveraging hardware acceleration and synchronized animation loops to maintain smooth visual transitions. It supports dynamic updates, enabling developers to modify displayed values in real-time without reinitializing the component, and provides lifecycle hooks to trigger custom logic during animation sequences.

Users can adjust visual properties such as colors, line thickness, and background styles to meet specific design requirements. The component is built to scale across different screen resolutions, ensuring a consistent appearance in responsive dashboard environments.
