Thanks! One of the big changes when I went from Java applets and Flash applets to HTML5 (around 2011–2012) was that I wasn't limited to only the diagrams being interactive, but I could make the rest of the page interactive too. I can change text and sample code. I can also embed widgets into text and sample code. An example is [1] where you can see the draggable numbers in the text and in the sample code, and those will change the diagram.
