Paper.js for Creating a Chain Effect in React TypeScript

The chain effect involves creating a series of interconnected shapes or objects that respond to user interaction or animation. Each element in the chain is connected to the next, creating a fluid and dynamic visual representation that can be manipulated or animated in real-time.

You can customize the appearance and behavior of the chain by adjusting parameters such as segment length, color, and thickness. Experiment with different settings to achieve the desired visual effect for your application.
