I'm building a clustering algorithm and need to visualize how data is distributed and relationed.
For this, I'm thinking in histograms (numerical and categorical data) and scatter plots. If possible, a 3D like plot like http://www.opendx.org/inaction/datamining/images/original/mci3.jpg would be nice, but is not required.
I'd like to be able to generate the plots from my code (My experience in C++ is limited).
Is there a simple package to achieve this that you can recommend?
My searches returned:
- boost graphics library
- ROOT (CERN)
But none of them seemed like the best candidate.
What suggestions do you have?
I'm coding in Linux 64bits, with gcc (g++).
