Besides libraries, Eastwood Charts is an Open Source compatible version of Google Charts. It uses encodings that match the Google Chart API and adds its own features such as trendline overlay, 3D effects for bar charts, etc. Eastwood Charts install on its own Java Servlet server and won't send their data to Google for processing.

Famous quotes containing the words open and/or source:
“[Panurge] spent everything in a thousand little banquets and joyous feasts open to all comers, particularly jolly companions, young lasses, and delightful wenches, and in clearing his lands, burning the big logs to sell the ashes, taking money in advance, buying dear, selling cheap, and eating his wheat in the blade.”
—François Rabelais (1494–1553)
“As a means of contrast with the sublime, the grotesque is, in our view, the richest source that nature can offer.”
—Victor Hugo (1802–1885)
