I have written a few C programs that are pretty extensive. I am looking to draw a flow chart/ER Diagram of how the header files are called and which call to which. While I could use Visio and draw this in a few hours, I am looking to make an interactive diagram. I have started one in Python using Imagine Magick but I am wondering whether Java/JavaFX/JavaGraphics would be the best way to go about this task. Any suggestions for the most efficient way to make a program that will draw a diagram of my large scale project?
NOTE: Python has worked thus far and it has drawn a small scale diagram with arrows to each relation but it is slow.
