A Quick Look at Lots of Songs …

Songs by year, rating and genre

iTunes information about my songs, showing year, genre and my ratings

A quick visualization of the songs in my iTunes database. I was curious to see if there were any sweet spots in my listening history. As always, showing correlation between three different variables is hard, and here I wanted one dot per song, so the density is quite high (clicking on the image to show it full size is recommended).

Perhaps the most interesting thing for me personally was that I though i liked Alternative music more than I actually appear to. I notice especially that the 2010-2015 bin for mid-value rating is dominated by Alternative!

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?
