Google Labs has released the Google Chart API to allow the dynamic generation of graphs that can then be included in your web page without the need for installing any new software. For example, if you copy&paste the following line into your browser, Google will generate the graphic chart on the fly for you and return the image. You can edit any part of the line and see the changes happen automatically.
