This is possibly one the most sparse infographics I've ever seen. There's only 5 units of information, and they aren't particularly engaging or related either.
They're also not accurate. The information is just taken straight from yclist.com, which is inaccurate in parts and not up to date. For example Loopt which was acquired 2 weeks ago for $43.1m is not included in this.
As far as I know the reddit price has never be disclosed and the $15,000,000 is an "estimate" (based on what? who knows).
Thanks for the feedback. The infographic will be updated accordingly.
