For an article titled “The decline of BlackBerry in one chart” you’d think that it’d be a well-designed intuitive chart that emphasizes the decline of Blackberry. Instead what’s presented is accurate but unintuitive and could easily be titled “The decline of Palm in one chart” or “The decline of Windows Mobile in one chart” or even Symbian. There’s no visual hierarchy—the main idea isn’t leaping out of this graph. (And sometimes design is as much about what you don’t show.) And if you’re really bent on showing all the big players at once there are more compelling ways to do it than this. I normally wouldn’t feel compelled to comment on something so small but it’s... It’s the TITLE OF THE ARTICLE!
