Using the Digg
API, I grabbed the top 10 most-dugg stories of the day (by midnight)
for the past year - May 24, 2007 to May 23, 2008. I then rendered
a series of tree-ring-like visualizations (moving outwards in time).
Rings are colored according to Digg's eight top-level categorizations
(see key at bottom of page). Ring thickness is linearly proportional
to the number of diggs the story received. I also made a pair of
visualizations using Digg's entire archive, which goes back to December
1, 2004.
Because the rings are cumulative, variations
in digg volume (within the top 10 stories) can be seen. For example,
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).
For unknown reasons, some days have fewer than 10 top stories.
This doesn't affect the visualization much aesthetically, but I
wouldn't trust it for detailed quantitative analysis!
If you want a copy of the data or have a cool visualization idea,
