Graph
Note: data has been smoothed over 5 days using median function.

Terminology explained...
	probability: The probability of observing variation as big or greater due to chance.
	MAD: [Median of absolute deviations (from median)](http://en.wikipedia.org/wiki/Median_absolute_deviation)
	Warning! The Chirp will not resend messages for a week unless something changes.
	~samples: An approximate number of daily observation (the median of single day of counts in all bins of the histogram over the last 7 days).
	~users: An approximate number of unique users per day (the median over the last 7 days).
