Integrating RRD data with JS plot libraries?

Hi,

Has anyone looked at ways of doing this?

I've been looking at the flot library [1] although there are many
others that aim to achieve the same sort of thing. I'm guessing that
graphs over a large number of sample buckets need to reduced to a
sensible number of points, possibly collecting a new set when zooms
are done.

What's the best way to get RRD to spit out a series of data points as
text? At the moment I'm using the RRDs perl module and doing a manual
RRDs::fetch() and iterating through the returned @$rdata array but
that does seem a little clunky, especially if I want to take advantage
of the flexibility of the graph definition grammar.
