RGraph can be used for free under the GPL or if that doesn't suit your situation there's an inexpensive (£129) commercial license available.

These are some of the example demo pages that come with the download archive. They run as soon as you extract it and are located in the demos/ directory. The majority of them run using just the RGraph libraries though a few do use the Google CDN hosted jQuery library.

There's over 1000 demos in the download archive - so when viewing the list of them in Google Chrome you can use the LinkClump Plus extension to make opening 100 (for example) of them at once a breeze. Similar extensions are available for other browsers.
