Graphing & plotting suites

Hi, I’m just wondering if anyone knows what restrictions there are, if any, for me to set up software that will let me generate on-the-fly graphs/charts/plots. I’m thinking along the lines of like gnuplot or R or some PHP-plotting library.

If there ARE restrictions, what alternatives are available (besides Graphvis, as that looks like it only does nodes–but I could be wrong, do let me know if I am)? What is the panel using to create those statistical visualizations?


The only real limitations here are:

  1. No persistent processes (i.e. left running all the time)
  2. Not a CPU hog (they’ll let you know if you’re pushing the limit)
  3. Legal in California
