2. Moodgrapher plots the mood levels reported by LiveJournal users in their posts.
* Use Moodgrapher to compare the "happy" mood level versus "sad" during the period from 9/1/2006~9/30/2006.
I wonder why Sep. 4th reaches the peak of the graph.I GUESS this is the reason "Deaths:2006/9/4 - Steve Irwin - Australian naturalist and TV personality. (b. 1962)". Steve is one of my favorites on TV shows.
* Can we justify that people drink more during the weekends?
According to the calender, one of the peaks of the wave is Sunday(9/17), the next one is Saturday(9/16). For a reasonable guess, weekends are the days for people to relax ,and of course, to get drunk.
