Here is a little feature in Matplotlib that I never saw before: stacked bar plots with tables attached. Perhaps too ugly for my Iraq Mortality stacked bar charts, but definitely handy for exploratory work.
I learned about it because it doesn’t work in `mpld3`… just one more benefit of being part of an open-source project. It would be so cool to have a `mpld3` version with some interactivity included, since interactivity can address one pitfalls of the stacked bar chart, the challenge of comparing lengths with different baselines.
It’s not quite d3-broke-and-made-art quality, but I like the plot in this bug report: https://github.com/jakevdp/mpld3/issues/274#issuecomment-68576519
I had an inspiration to make something a couple weeks ago for #MakeSomethingDay (the productive alternative to #BuyNothingDay). It is a finger-painting app that neighborhood kids have been enjoying. http://bl.ocks.org/aflaxman/a31763011f9da46fc6d2
A new issue of Stephen Few’s Visual Business Intelligence Newsletter is out. I love categorizing things like this. I have been thinking of interaction very differently than he has, but everything else seems sensible to me.
I helped judge a plotting contest for the Scientific Python conference last summer. Who won? I don’t know, and a short web searching binge didn’t find out. A lovely plot took 3rd place, and every entry is here (with sourcecode). Good stuff for seeing how different groups do different tricks, and for checking what still doesn’t work in mpld3.
The thing about interactive data visualization is that its not always clear what is useful because it excites my reptile brain, and what is useful for more logical reasons. But I was asking a colleague to add some callouts to a (non-interactive) figure recently when I realized that this is a chance for interactivity to be _obviously_ useful. These finishing touches on a graphic often take me tons of time, and using a command-line plotting program just can’t be the right way to do it. How about an mpld3 plugin that lets me add text callouts interactively? And when I’m done, it can “save” the callouts, by creating the necessary Python script to generate them again? Here it is, in a notebook.
