EagerEyes Shorts

Musings on visualization, photography, programming, etc. that are too long for Twitter but too short for (or don't fit) my visualization website, EagerEyes.org. Part of my vanity website, kosara.net, which is most notable for hosting my list of publications. If you still want to know more, see my university page at UNC Charlotte, and/or follow me on Twitter.

Why does a salad cost mmore than a Big Mac?

It’s a good cause, but the chart badly distorts the data. See my recent March Chart Madness criticism roundup for an explanation (it’s about 2/3 down the page).

nice, non-overwhelming application of parallel sets.

Yeah, I wish. This is more likely a Sankey Diagram, which is used to indicate flows of energy, money, etc. We might look into using curved lines in the future; we should also figure out a better way of labeling, especially for larger display and/or print. This gets a lot trickier when doing it automatically and for potentially large numbers of categories and combinations.

Combining Parallel Sets/Sankey with bar charts is not a bad idea, but I’m not sure I like the way they do it here. Having the bars vertical would have made more sense to be able to compare them better.
