I am currently doing research for an upcoming visualization that will trace the development of ideas through a conversation. Unable to find processing code to create an area chart, I decided to write my own. I imagine if I looked, there is something out there, but I also wanted something I could completely control to change the appearance of. Hopefully you will find the source useful in a project of your own. The image below is an example of the output from the code.
