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:
“Culture, the acquainting ourselves with the best that has been known and said in the world, and thus with the history of the human spirit.”
—Matthew Arnold (1822–1888)
“The history of any nation follows an undulatory course. In the trough of the wave we find more or less complete anarchy; but the crest is not more or less complete Utopia, but only, at best, a tolerably humane, partially free and fairly just society that invariably carries within itself the seeds of its own decadence.”
—Aldous Huxley (1894–1963)
“The history of the genesis or the old mythology repeats itself in the experience of every child. He too is a demon or god thrown into a particular chaos, where he strives ever to lead things from disorder into order.”
—Ralph Waldo Emerson (1803–1882)
