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:

    Why the jailer does not leave open his prison doors,—why the judge does not dismiss his case,—why the preacher does not dismiss his congregation! It is because they do not obey the hint God gives them, nor accept the pardon which he freely offers to all.
    Henry David Thoreau (1817–1862)

    We are threatened with suffering from three directions: from our own body, which is doomed to decay and dissolution and which cannot even do without pain and anxiety as warning signals; from the external world, which may rage against us with overwhelming and merciless forces of destruction; and finally from our relations to other men. The suffering which comes from this last source is perhaps more painful than any other.
    Sigmund Freud (1856–1939)
