This applet uses some parts of JFreeChart (jcommon-0.5.2.jar, jfreechart-0.7.0.jar), a freely available chart construction class library for Java 2. It also uses the package cern.colt library (Copyright (c) 1999 CERN - European Organization for Nuclear Research) of the Colt Project. Colt Project provides a set of Open Source Libraries for High Performance Scientific and Technical Computing in Java. In our applet, we have used its random number generators.
