ZingChart
ZingChart was born in 2008, during the development of a deep web analytics system. The company needed to add standard charts to the mix, but existing Flash and canvas based graphing systems couldn't keep up. They kept buckling under the volume of data provided and lacked the required flexibility. One year later, ZingChart was released and it keeps growing in features, flexibility and popularity.
