     There's JFreeChart <http://www.jfree.org/jfreechart/>, which
can draw many kinds of charts in Swing applications. I think it
can also render them as PNG or PDF.  The gotcha (last time I looked)
is that the library and JavaDoc are free, but the "How To" book
costs money.

     Google Charts <https://developers.google.com/chart/> lets you
embed graphs in HTML documents, using Javascript libraries.  You
can write the HTML from any language you choose, including Java,
and any modern browser can display them (without needing Java).

     OpenOffice.org has API bindings for various languages that would
let you generate OOo documents directly from your Java code. It's
quite un-Java-like, possibly because of the other language bindings
it needs to support. I don't know whether it works with LibreOffice,
or whether LO has similar API's.
