Try dotty.exe to create graphs. Use graphviz open source.

Theoretically you'd do that following these steps. Actually you have to first learn how to work with particular parts:

  1. Save these coordinates to an array or a List.
  2. Draw the content using javafx or any graphics library.
  3. Read the: https://community.oracle.com/thread/2450090?tstart=0
  4. In case of using javafx, you can capture its canvas with canvas.snapshot(..)
  5. Save the file using ImageIO.write(SwingFXUtils.fromFXImage(wim, null), "png", file);
  6. Hooray!

I recommend you to start with learning all about variables, data types, arrays, loops and lists/maps. Don't start with 2D drawing unless you can handle with data :)
