EZGraph substitute for Java

[Alexander,J]

As I understand it, the Java interface for Swarm provides a Java wrapper around 
the underlying
Objective-C based code.  (I suspect there's much more to it than this, but is 
this right, at least as a first approximation?)  If this is correct, then is it 
also right that EZGraph, EZHistogram, and so on cannot be used as independent 
Java applets?
 
I ask because I've started to write some models in pure Java for embedding in 
web pages, and I cannot find any freely available classes or jars that provide 
the functionality of EZGraph, EZHistogram, and so on.  The graphing libraries 
I've found tend to be expensive or limited (i.e., they read data from a file 
and cannot be updated dynamically like EZGraph and kin).  Does anyone know of 
any Java applets that would provide functionality similar to EZGraph?
 
Cheers,
 
Jason
