Chris Harrison is a doctoral student in the Human Computer Interaction Institute at Carnegie Mellon University.At his site you can find several interesting visualisation projects.

For example these ones:

A Bible visualisation


“The bar graph that runs along the bottom represents all of the chapters in the Bible. Books alternate in color between white and light gray. The length of each bar denotes the number of verses in the chapter. Each of the 63,779 cross references found in the Bible is depicted by a single arc - the color corresponds to the distance between the two chapters, creating a rainbow-like effect.”

A Digg visualisation


“… when stories are broken down by day, we can see that Sunday has fewer diggs than Monday. Also, if you look closely, you can see that the volume of diggs has increased overtime (i.e., rings become thicker). Additionally, we can see how story categorization has evolved (or perhaps how the Digg community has changed), especially in the visualizations using the full archive. This is partially due to the fact that Digg has added new categories overtime (it started very technology centric).”

An Amazon visualisation


“… visualization is a huge mosaic of book covers, tinted by their respective category colors…”
