I modified the underlying code from notations that were included in Draw.io to look like data flow diagram notation. However, since I made the video, one of my students introduced me to Lucidchart.com. It's a free application that includes the data flow diagram notation and is as easy to use (or easier) than Draw.io.
Please how did you get the diagrams for the data flow diagram onto scratchpad?
