Dygraph with specified annotation
Annotations are bound to specific series in the input data. If you have
only one series or if you define annotations immediately after a call to
dySeries then you need not specify the series explicitly.
Otherwise, you should use the series parameter to indicate which
series the annotation should be bound to.
Annotation event handlers can also specified globally (see
dyCallbacks).
See the online documentation for additional details and examples.
