4. Including applets#

4.1. SVG#

Figure 4.1 shows how you can geometrically add two arrows in a plane. The image is a SVG image rendered in the browser.

4.2. Applet#

It is of course much nicer if you can interact with the image. One way of adding interactivity in the browser is through applets.

4.3. Credits#

Vector applet developed by Beryl van Gelderen, integration of applet in Jupyter book by Julia van der Kris and Abel de Bruijn, all as part of the open linear algebra book under development by PRIME.

4.4. HTML files as applets#

As we can now integrate other HTML files (with their own style sheets and JavaScript), the possibilities are endless. I can for example include this simple website on which you can practice your arithmetic.
