Thomson Reuters published a rather abysmal infographic showing the "bowl of spaghetti" that is current flurry of patent-related suits in the mobile communications industry. So, inspired by a comment by John Firebaugh, I decided to remake the visualization with something that much more clearly conveys the suits. That company in the center? Yeah, it's the world's largest, so little wonder it has the most incoming suits.
Implemented in D3.js.
