As somebody who tries to consume as much visualisation work as possible, I always get a little extra joy from seeing clusters of the same techniques emerging. One such recent trend has been the use of simplified slope graphs.
By ‘simplified’ I mean they are stripped right back to a simple function of just showing the direction of change between two points in time, there are no axes and no other chart apparatus, just the trends.
I’m kind of iffy on it. I do like the map showing behavior of states over time, but the first visual had too much going on and the third visual had too much whitespace for my taste.
