Hi , 
    I'm looking for a Java based solution for my canvas problem
TCL/TK is not able to handle 3million rectangles on a canvas !
 
https://groups.google.com/forum/?fromgroups=#!topic/comp.lang.tcl/Dxh4KyOOojY 

" 
Today I had to visualize a huge Data Structure with 146k nodes 
and each node is a set of polys/rectangles >20 

I've drawn everything on a Canvas , Appximately 3 million objects were created 
All my operations Zoom , Scrolling , Moving Objects on this Canvas have become very SLOW 

I've tested the code with 100 nodes , everything is working fine at that level 
When I increase the DS , I'm looking at these issues . 

Any suggestions previous experiences on how to improve the speed ? 
 " 

Can JavaFX , Java/Swing Handle that much data ? 


Thanks
