Does anyone know a free framework for visualizing decision trees that allows the use of events (double-click a node for additional split)? I am interested in using these events to trigger additional calculations in R/Python/other.
Background on my request: I need to be able to efficiently incorporate business rules with a optimized splits (through the usual algorithms) into a single tree.
I know there are proprietary tools for this dynamic tree building (SAS,FICO,Angoss,etc) but I need a free visualization framework to pair up with an existing solution.
I tried adapting google’s visualization API for organizational charts, but it does not fully support the events I had in mind; and also calling R from Javascript seems a bit of a rocky road.
MANY THANKS FOR ANY FEEDBACK!!!
As far as I have been able to dig there are 2 tools that might work as the framework for me to build the GUI I need:
http://www.graphviz.org/ and http://processing.org/
If you have any other options please post them!!!
