This visualization was created by the same person as the first text message visualization. I like this one a little bit more, it shows some patterns and gives more of a story. Though I am very confused by the y-axis, it appears to be inverted (from the way I would expect time to be). I almost feel this is deceptive, I had to examine this graphic for a fair amount of time before noticing that.
