Reader Aleks is none too happy with the sets of charts here (what looks to be an online dating site). It's hard to take these seriously but the people who made them sounded pretty serious.
Pay special attention to the whimsical placement of the horizontal axis. Are those negative numbers? Positive columns floating mid-air, and up-ended?
