 ## Graphical Output
 
 Sometimes, you want to produce a `canvas` image instead of doing numeric computations. To achieve this, set the `graphical` flag to `true` and the output dimensions to `[width, height]`. The thread identifiers will now refer to the `x` and `y` coordinate of the pixel you are producing. Inside your kernel function, use `this.color(r,g,b)` or `this.color(r,g,b,a)` to specify the color of the pixel.
