Wikipedia Recent Changes

Wikipedia Recent Changes Map shows a good example is a good, clean, simple implementation that addresses the question:

“How is Wikipedia being Edited right now?” 

Some of the features of this visualization that work:

  • Filtered data — the potential data size is huge, and grows as we wait, so the display only shows the most recent events, both on the map and the list below it
  • Multiple linked views — data is shown geographically on the world map, and as a list of events below. This is preferable than trying to have one combined view as each view supports a different set of tasks, and combining them would complicate those tasks (WHERE are the changes coming from? WHAT is being changed?)
  • Not using graphics — the report on what has changed is a simple scrolling text view; since the dat is textual, and it is ordered, a simple list of text makes sense.
  • Different fade-out rates — Using the color for the country to show the most recent changes, and then fading that out in synch with the text description, focuses attention on changes very well. Leaving the dots behind for the changes allows us to keep a longer-term trend in mind.

As a map geek, I might prefer a different projection for the whole earth map; maybe WinkelTripel?

About workingvis

Visualization is the science of making pictures out of data so that they inform the viewer and allow them to understand the data and take action based on what can be seen. I create new methods of interacting with data using a computer interface and try to understand what tools help people model their data and find patterns and unusual features. I have a background in statistics and statistical graphics, and work with computer scientists as well as statisticians. My particular interests include research into: * Fundamental methods for interaction with data views * Statistical methods to improve or motivate visualization design * The interface between statistical models and statistical graphics * Visualization of large weighted graphs * Ways to use knowledge discovery techniques with visualization Specialties:visualization, research, statistics, statistical modeling, graphics, information visualization, agile development, spatial statistics, time series
