Try the SydJS list. You're likely to get good replies there for JS questions.
Since canvas in itself is stateless, the only way to do it is keeping the state in JavaScript (i.e.: keep an object around to store the graph). You can then check the object's state, if say, you set an attribute when the graph is fully rendered. And yes, depending on how effectively and correctly you want to do this, it gets more complex than my suggestion.
