m" parameter. For example to
set the max memory for Treemap to be 256M, change the run.bat file to look like this:
java -Xmx256M -jar Treemap.jar
If you don't specify a maximum size, then the default
maximum size is taken as 64M. If Treemap doesn't have enough
memory, it will display a message indicating that it is
out of memory.
(Note: Since Treemap 4.1 out of memory errors are handled
more smoothly than earlier versions. For this reason,
the use of log files has been discontinued.)
If you are dealing with extremely large trees, you might want to look at this project:
Visualizing a million items, and also look at the results of
the InfoVis Contest 2003.
