  • Thanks Rob, could you help to explain how it works? where are data from? – Shawn Guo Jul 12 '16 at 15:08
  • @ShawnGuo The only way I could find to get the data was to just lookup every single question and store it's tags in my own database. Due to the quotas on the Stack Exchange APIs it took a few weeks to collect all the data but now that I have it I just have a script that runs once an hour to pull in any new questions. You can take a look at it here github.com/robianmcd/tag-trends/blob/master/node/so-crawler/… – rob Jul 13 '16 at 0:51
