About the TDG

The DS5 Productions Tree Diagram Generator is a mathematical tool, aimed at students, teachers and examiners who wish to avoid the hassle of drawing complex probability tree diagrams by hand.

With a real-time point-and-click interface, you can create any number of stems and directly input probabilities and labels onto the canvas.

The intuitive GUI makes it easy to export your diagram in any of several popular graphics formats (BMP, JPEG), print it and copy it directly to the Windows clipboard.

The TDG Distribution includes a help file and example diagram files.
