Algorithms are a fascinating use case for visualization. To visualize an algorithm, we don’t merely fit data to a chart; there is no primary dataset. Instead there are logical rules that describe behavior. This may be why algorithm visualizations are so unusual, as designers experiment with novel forms to better communicate. This is reason enough to study them.
But algorithms are also a reminder that visualization is more than a tool for finding patterns in data. Visualization leverages the human visual system to augment human intellect: we can use it to better understand these important abstract processes, and perhaps other things, too.
" I started this because a couple of months ago I saw someone visualizing movies in the form of a barcode. Every couple of seconds a frame's 'average' color was determined, and put together to form a colorful barcode, that nicely shows the color usage in that specific movie. I liked the result, so I wanted to reproduce this for a couple of movies I had laying around. "
