Here’s a simple example of how to create a 4x4x4 cube using HTML Canvas and JavaScript. This code will draw a 3D cube with a sine wave oscillating vertically.

Cube and Sine Wave
```
### Explanation:
1. **Canvas Setup**: A canvas element is created with a width and height of 500 pixels.
2. **Drawing the Cube**: The `drawCube` function creates a simple 3D cube using basic lines.
3. **Drawing the Sine Wave**: The `drawSineWave` function creates a sine wave, with the amplitude representing the side length of the cube (4 units).
4. **Rendering**: The `draw` function clears the canvas and calls both drawing functions.
