+[[https://www.geogebra.org/ |Geogebra]] is a graphing and geometry tool I've been using since my teaching days.  I always found it to be very useful to display concepts that are hard to visualize on a static page.  However, it is a lot more than a simple animation since people can interact with it and move things around.
 In the past, I had to export Geogbra files to html5 to embed them, but the process was pretty clunky and time consuming. I searched the Dokuwiki plugins but all the ones listed are too old and don't work anymore.  Finally, I created my own using some general instructions for [[https://wiki.geogebra.org/en/Reference:GeoGebra_Apps_Embedding |embedding Geogebra files]].  This is my first plugin and a bit of a cheat: I basically took the existing [[https://www.dokuwiki.org/plugin:color |Color plugin]] which is pretty simple, studied it to learn a bit of the syntax and modified it until it did what I needed.  However, there's still a lot of code that I don't really understand and a few features that are missing.

 The syntax is:<code>

+{{ggb>/path/to/geogebrafile.ggb 740,300}}</code>
 Note that at the moment, if a path is used, it must use ''/'' instead of '':''.  The default dimensions are 800x400 if they are omitted.

 When two waves overlap, they add up together at every point.  Here, the <fc #4682b4>blue</fc> and <fc #008000>green</fc> waves are generated and add up together to form the <fc #ff0000>red</fc> wave.  You can move the blue and green waves and see the result.  To convince yourself that the red wave is really the sum of the blue and green waves, look at points <fc #4682b4>A</fc>, <fc #008000>B</fc>, and <fc #ff0000>C</fc>.  You  can move the blue or green waves by sliding their phase (<fc #4682b4>φ</fc> and <fc #008000>Φ</fc>) around.  You'll see that point <fc #ff0000>C</fc> is always the sum of <fc #4682b4>A</fc> and <fc #008000>B</fc>.
