Spatial data is data equipped with spatial coordinates. How those coordinates are given is another story we shall be looking at closely, following Ward et al.
Exercises / Assignments
Find spatial data on the web. As suggested by Ward et al., you could use the quakes dataset describing earthquakes that occurred on earth between 1973 and 2010. See the adequate [[http://geocommons.com/overlays/67834|GeoCommons web page]. (GeoCommons contains lots of other datasets you could use.) Use Tulip's plug-in to visualize spatial data on Google Maps directly within Tulip. Map node size and color to additional attribute (you could map the Richter index of the quake on node size for instance).
