title: PHP / AJAX toolkit to make a "live graph" (eg for tracing stock prices)
body: <p>how do i (after getting the right stock prices from a source) show it on a "live graph". i'm looking for a php/ajax toolkit that allows me to create that graph live?</p>
  
  <p>is that the right thing to use or a flash based solution is better?</p>
  
  <p>are there 3rdparty sites that offer to create live graphs given input data?</p>
