Tutorial 5 uses a drawing canvas for a whiteboard, so similar to this.

What you are asking about it more Vector drawing.

Yes. You could do it from scratch using SVG (see test/svg_demo.adb) but it is probably better to leverage existing JS libraries and just bind them using Gnoga.

I will likely at some point soon create a binding to : 

http://jsplumbtoolkit.com

Which is very much in line with what you want.

That is the beauty of Gnoga, you are now able to leverage every existing JS library out there and so are always able to create far richer desktop or web apps than any existing UI framework such as Gtk, etc. (BTW, you can easily turn any Gnoga app in to a Gtk app or Mac OS X app using the webkit widget with a simple recompile see the docs dir for the native gtk doc :)

With Gnoga, I'm like Lady Ada in a candy store, I can pick from thousands of open source or even commercial JS components actively developed and instantly use them for my projects or bind them for even easier use in Ada and by others.
