[OT] Choosing a javascript plotting framework

Monks, I humbly approach thee with a non-perl question, thus marked OT - Off Topic: How to choose a javascript plotting framework?.

The criteria are as follows:

Plot support: Be able to render line, pie and bar charts.
License: Preferably free and open source.
Cost: Preferably gratis or low-cost.
Technology: Preferably pure javascript (not rely on Flash or similar).
Multi browser support: Preferably a framework that works with most common browsers (e.g. Firefox 2 & 3, Internet Explorer 7 & 8, Safari, Google Chrome, Opera).
Extensibility: Possible to extend or override functionality.
Off line capable: Do not require internet access.

The frameworks evaluated (with shortcomings) to date are:

YUI Charts: Fails on pure JS criteria (uses Flash).
Protovis: Fails on Multi browser support (does not support IE).
DyGraphs: Fails on Multi browser support (relies on html5 canvas element which is unsupported in IE prior to version 9), line chart only.
HighCharts: Fails on license (commercial, proprietary), otherwise very rich in features.
FusionCharts Free: Fails on pure JS criteria (uses Flash)
Raphael Vector Graphics: Fails on (out of the box) chart support.

I seek the advise from the wider Monk crowd on options and possibilities I may have missed out on. Thank you.

I know there are many jQuery charting plugins which fit most if not all of your requirements. See flot or jqplot for example.	[reply]

One of interest/depth you missed: JavaScript InfoVis Toolkit.	[reply]

I can vouch for flot. I've used it successfully on several projects and found it very easy to use. It's built on top of jquery. It's 100% javascript, free, open source, supports all common browsers, doesn't require internet access, etc. The only requirement you specify that I'm not sure about is support for pie charts. I've never had to do those, and don't see any on the examples page... so you might check into that if it's a deal breaker.	[reply]

There is also flotr, based on Prototype (docs and stuff; "playground"). HTH, planetscape	[reply]
