Sunday (2/7) was pretty light for me in terms of data creation. I was traveling for most of the day, so most of the data I create regularly by browsing the web was eliminated. Here’s what’s left:

  1. A constantly running health app on my phone tracked and stored my location and some other sensor data.
  2. I was in a car for several hours, so I probably showed up on at least one traffic camera.
  3. I sent multiple texts throughout the day.
  4. Other passive data usage on my phone was also tracked.
  5. I participated in a singing competition which was recorded and will probably be posted online.
  6. I was in a group photo which will also likely be posted online.
  7. I listened to music on Spotify, which keeps track of what I play.
  8. I watched the Super Bowl, whose viewership, like other TV programs, is tracked.
  9. I watched a show on Netflix, which also keeps track of these things.
  10. I checked my email, informing the mail server that I’ve looked at the messages.
  11. I followed a link to a website that very likely tracks visits.
  12. I looked at some course websites to plan my week.
  13. I used electricity, which shows up on my bill each month through an electronic system.

I probably missed some things, but if a day in which I spent the majority of my time doing very little produces this, it would be a daunting task to enumerate every point of data I produce on an average day.

Visualizing Binary Data

Original visualization and Author’s comments

binvis.io isn’t so much a statement as an exploration of what files on computers “look like”. In essence, it takes a binary file containing arbitrary data and generates an interactive visualization which allows users to inspect regions of the file for values such as byteclass (useful for distinguishing text from other data, for example), local entropy, and byte-level details. Admittedly, the target audience of this presentation is likely technically-minded, but the key ideas apply to a lot of areas. To keep it short, I’ll go over just two of them.

BinVis

The first is the representation of parametrized data in 2D. Many visualizations try to present multidimensional data in 2D, often using 3D computer graphics and animation. This visualization tackles the opposite problem: presenting a 1D sequence of points in 2D. The author exploits spatial locality by clustering contiguous regions of similar type, but also allows simple sequential display of the data on the grid. He also explains the techniques he used right in the help menu.

The second feature is that information isn’t withheld. For credibility, a presentation should be verifiable by giving sources or making the raw data available. This visualization takes this idea a step further by showing the raw data directly alongside the visualization, albeit in readable chunks. An even cooler feature is that the data which the user is focusing on is highlighted in each of the components (see the screenshot above). This creates a visual mapping between the raw data and the presentation, a powerful technique for showing connections across levels of abstraction and inviting users to ask their own questions.
