Idea for an exercise: Build your own decision tree

Idea for an exercise: Build your own tree

Here is a possible exercise to help people build intuition: Show them just a small section of the data (maybe 10 data points), and have them build their own decision trees of dephts 1 and 2.

Could do this by showing the data on a 2-D graph, coloured by outcome and have users draw a decision surface by hand. Or write a widget that would let people play around with different decision models and see what happens.

This would be done before doing it with code for the entire dataset.

I would be happy to write this out and add it if you all think it's a good idea.
