I find the best way to approach this is to use SVG for the annotations, giving you a more flexible API (DOM interactions, styling, mouse movements etc), and WebGL for plotting the series data, allowing you to capitalise on the performance.

For an example, take a look at this visualisation:

You can see how the series and annotation are rendered on different layers in the code here:
