How to clean the past graph rendered?

[dpineiden]

Hello

The library is very good, it works fine. But i can't find now how to clean the canvas to render a new graph. Right now the new graph is added to the right.

That's all

Best regards°!

On my page http://graphviz.it website graph is cleared by setting string digraph G {\n\t\n} as a diagram source. Maybe it will be more convenient to add clear() method.
