What is the best way to draw different types of graphs with big data in a Java program? [on hold]

So I have a Java simulation that uses a terraforming algorithm to create a world and I want to be able to create graphs of the data that is generated. I want the graphs to be extensive and speedily generated. My previous idea was to implement R stuff into my program using the Runtime.getRuntime().exec("Rscript myScript.R"); method. However, I read that this method can take 30-40 seconds to generate the script. Is there any faster way to run R in Java? Should I abandon R for something else? I would like to use R if possible, but I could settle for another solution if it worked fine. Thanks!
