Which of course means it lacks the interactivity of a Flash-based chart, but it’s compatible with more platforms and is by far the easiest to implement. One drawback is that (at the time of writing) it does not support negative numbers without cheating. [...] [...] The Google Chart API is fun, easy, and doesn’t rely on Flash at all.

If you look at what Google has used this charting for (Trends and Analytics), you can see why they made this decision. They don't want people passing thousands of data-points to a graph that only has, say, 250 pixels. Still, it makes the API hard to use. There needs to be some intermediary, and I'm sure there will be soon.

It's pretty kludgy, I agree, though. It'd be nice if Google didn't require this scaling and offsetting. I've been investigating using the Charts API in the SpamAssassin rule-QA backend web app, and it's not great... we'd write nearly as much code to use our existing gnuplot-based charting!
