Simulate a chaotic double pendulum on a canvas using the correct equations of motion, drawing the arms and a colorful fading trail of the tip.

**Simulating Double Pendulum** I'm focusing on rendering the chaotic motion of a double pendulum. The plan is to draw the arms directly onto a canvas element within a single HTML file. I'll also implement a fading trail for the tip's path, ensuring no external dependencies are used. **Calculating Motion Parameters** I've been diving into the equations of motion. My focus is now on implementing these equations in JavaScript, setting up the canvas and styling it, and then developing the animation loop for rendering.

The double pendulum simulation is complete and contained within `index.html`. It uses the coupled equations of motion with numerical integration, drawing both the physical arms and a colorful, fading trail that represents the path of the second mass. You can open `index.html` in any modern web browser to view the simulation.
