Chris McDowall is a cartographer and data enthusiast from New Zealand, and author of the SciBlogs Seeing Data site.
This proved to be an extremely popular visualization but, as is the designer's prerogative, Chris identified certain features that he would like to refine in due course.
He has now completed most of these updates and a second iteration has been published [sciblogs.co.nz/seeing-data/]. You can view the animated movie the below or, if you are viewing this post via a RSS feedreader, by clicking here.
This updated version includes a number of improvements behind the scenes to the geometry data, which may not appear obvious to the untrained eye. The most visible and enlightening improvement is the distinguishing of transport types using different colours for buses (teal), ferries (blue) and trains (red).
Keep an eye out on the Seeing Data blog, over the new few days, for more details about how the animation was created, which should prove very interesting.
