Aardbevingen NL - DatavizFest

Basic starting boilerplate for DatavizFest participants who want to work with the Earthquake data using D3.

This setup already loads in the data, and has two very basic approaches: a time based approach, and a geo based approach.

Just uncomment the lines for the approach that you want to use to get started, or you can come up with your own approach of course!
