A heatmap, based on more than 9000 couples, registered in vk.com social network, popular in Russia. This data had been scarped, using special vk.com API, where it’s possible to fetch users personal info (if he chose not to hide it). Also API provide ways to request list of friends of a person, list of users in the groups etc.. I am not sure if similar API exists for facebook?
You can choose different options for viewing this table:
- Default heatmap, blue-red hues, where blue means lower than average (total amount / 144), red — higher than average: : http://complexpicture.com/apps/zodiacs
- Russian version: http://complexpicture.com/apps/zodiacs/?lang=ru
- Relative red hues, I was thinking to make it default, but blue-red distribution seems to be more expressive: http://complexpicture.com/apps/zodiacs/?quant=rel
- Absolute distribution, where shows comparison of absolute values, which is maybe less deceptive, and which probably states, that zodiacs matching is a myth: http://complexpicture.com/apps/zodiacs/?quant=abs
