We've just got all the sort and filter options working correctly on the test site, meaning you can shape the tree by Name, Age, Location, Gender and Pledge!

There are still a few bugs though as you need to refresh the page to try a new sort. Also you can't zoom into any branches yet or click on the leaves.

Tooltips are now working so when you rollover a leaf it shows the user, their age range and location. The background colour of the tooltip corresponds to their gender (blue for boys and pink for girls).

It's taking shape - literally!
