[Newbies] report / graph generator

Hi everybody! I am currently looking into using squeak for data analysis at work. At the moment, I mostly need to postprocess data files created by other programs and put graphs and overview tables into some kind of PDF report. Are there any existing solutions for such tasks? Later, I would like to move some of the code for data analysis from older C programs to Smalltalk. Is there a capable matrix/vector library, like numpy/scipy for python?

Thanks, Danny
