Chapter 2 already has a visualization of an algorithm; what are the concepts that we can visualize? My first thoughts:

1. Table driven agent: show a table of the percepts and the resulting action. Given the state of the world, show which table entries would be activated.
2. Rule driven agent: show a sequence of rules and the resulting action. Given the state of the world, show which rules would be activated. Follow the action from the first matching rule.
3. Model driven agent: show the internal model of the world also. I'm not sure if there's something meaningful with the vacuum cleaner agent though.

I don't know if these visualizations will be useful or interesting but I would like to try them and see.
