Back in the fall of 2006, I decided to write a diagram editor in the form of a Java applet that would allow the user to generate TeXdraw code to be used in a LaTeX document. Sadly, however, browser support for Java applets would soon be on the wane, and so I gave up on the idea of maintaining a web site for my diagram editor.
Eventually, in the spring of 2024, I thought that it might be interesting to implement the applet, or some variant of it, as a modern web application. The result of this (by now largely complete) effort is available here.
