History
Originally, Google offered charts as a PNG image of a chart from data and formatting parameters in an HTTP request.
But since April 2012 Google is now using SVG (VML for older browsers) to draw the charts. The Google Image Charts API is deprecated (but still works).
Originally it was an internal tool to support rapid embedding of charts within Google's own applications (like Google Finance for example). Google decided it would be a useful tool to make available to web developers. It officially launched on December 6, 2007.
Currently, line, bar, pie and radar charts, as well as Venn diagrams, scatter plots, sparklines, maps, google-o-meters, and QR codes are supported.

Famous quotes containing the word history:
“No matter how vital experience might be while you lived it, no sooner was it ended and dead than it became as lifeless as the piles of dry dust in a school history book.”
—Ellen Glasgow (1874–1945)
“A man will not need to study history to find out what is best for his own culture.”
—Henry David Thoreau (1817–1862)
“The history of work has been, in part, the history of the worker’s body. Production depended on what the body could accomplish with strength and skill. Techniques that improve output have been driven by a general desire to decrease the pain of labor as well as by employers’ intentions to escape dependency upon that knowledge which only the sentient laboring body could provide.”
—Shoshana Zuboff (b. 1951)
