Alternatives to Google Chart API

[Thomas David Baker]

I've been doing some stuff with the Google Chart API.

It's lovely.

But it's just too limited.

The amount of data that will fit in a URL and within the size
constraints they offer is just not that great.

Among many other things, I want to create a horizontal bar chart with
> 100 entries with a legible text label for each bar. It's not going
to happen within 1000x300 pixels.

So my question is, what is just as lovely as the Google Chart API but
will let me make bigger graphs? There's absolutely no requirement for
it to be a web service. I'm comfortable with most popular programming
languages but a nice PHP API is a big plus. It certainly has to be
completely automatable.

A bit of googling brought up a few alternatives but they mostly look
ugly. I'd rather have a real recommendation from someone whose used
them before.

Thanks!

amCharts and Open Flash Chart are both worth a look.

amCharts offers zooming, which can help with a lot of data. See WikiChanges for a good example (click and drag):

Both allow rollovers.
