How to generate Google Search result's time line image

Question

Hi,

Can you please tell me if there is any open source library which generate 'timeline image' in Google Search result? (see below as an example):

Thank you.

Answer 1

That image is generated by Google Chart Server. You can use this from your web applications. I'm not aware of an open source equivalent.

Answer 2

These graphs are similar to sparklines which were based on thoughts by Edward Tufte.

There's quite a few open source libraries which can generate these, including JQuery. You can find more implementation links by searching Google for "sparkline [language]".
