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:
“Indeed, the Englishman’s history of New England commences only when it ceases to be New France.”

“The history of mankind interests us only as it exhibits a steady gain of truth and right, in the incessant conflict which it records between the material and the moral nature.”
—Ralph Waldo Emerson (1803–1882)
“Hence poetry is something more philosophic and of graver import than history, since its statements are rather of the nature of universals, whereas those of history are singulars.”
