In need of knowing the best time to post on Facebook I wanted to see all the data on a couple of neat charts. So I started gathering data by logging in to Facebook Chat just to take a peek on how many friends were online (later I started taking note of gender and locale used).
Now I can check what are the busiest hours on Facebook, according to my friends.
Changes to Chart.js:
- made the Line chart stackable
- created a "concentric circles" chart
- created a weekday/hour bubbles chart (like the commits chart on Github)
