* You can add your own method to the canvas. For example if you want to draw a pie chart,
* you can create your own pie chart function and ship it as a Raphaël plugin. To do this
- * you need to extend the `Raphael.fn` object. Please note that you can create your own namespaces
- * inside the `fn` object — methods will be run in the context of canvas anyway. You should alter
- * the `fn` object before a Raphaël instance is created, otherwise it will take no effect.
