# Julia Set
[View this example online](https://webassembly.studio/?f=qmg1c6dbjos)
This is an example of more complex computations needed to generate a fractal (Julia Set).
It's also an example of direct interaction with CanvasRenderingContext2D's API via `#[wasm_bindgen]` macro.
You can build the example with:
```
$ ./build.sh
```
(or running the commands on Windows manually)
