This visualisation by John Burn-Murdoch of the FT caught my eye.
What I like about this is how he had to think outside the box to show changes in rankings over time for a selection of tennis players. Lines would be like spaghetti. Stream charts suck. Parallel coordinates: you cannot be serious. Having different symbols, sizes or colours all use poorly-read mappings of data to visual dimension. So, something new was needed. And, of course, it has to conform to house style. And in doing so, he uncovers some nice little stories that are not so clear from the stark headlines, about runs at number one and comebacks, and whether it really is tougher than it used to be. Sweet annotation too. John has absolutely aced this one. (Sorry, couldn’t resist.)
