Your call, of course, but I would consider using a canvas widget.

If you make a canvas object for a data series (ie. the single object
would draw all 1000 points in a series) you can avoid having to build
huge canvas object sets.

Plus using the canvas framework will make interactivity easy (or
easier), since it already has a nice framework for handling
selections, dragging, optimising updates, and so on.

Finally your users will thank you for not reinventing a lot of the
canvas API and forcing them to learn it.
