This page shows the usage of the crossword program from a number of points of view.
The following graph shows the usage, per hour, over the last three weeks. Current time is to the right. The vertical axis shows the number of puzzles generated per hour, and the horizontal axis shows the date.
It is clear that this follows a daily cycle, indicating that most of the use is in the "daytime" of the western hemisphere, probably the USA.
This also shows a weekly cycle, with less activity on weekends, and more on weekdays. This program is used for school (teachers and students), and the weekdays are when they do things.
Looking at the daily graph shows the weekly cycle. Each hump during the school year is a week of activity, and the low periods are the weekends where the puzzle doesn't get used as often as during school days.
The weekly graph shows the school year. When school is in session we will have a much more activity then in the the summer and Christmas. There were 1,830 puzzles made today (so far), 89,357 puzzles made in the last month, and 657,539 puzzles made in the last year.
As you can see, each year's profile is much like previous years. With growth, the more current years will be above the earlier years.
The yearly graph shows the puzzles made in the previous 52 weeks, for each week. This should filter out all of the fluctuations made over a school year, and should represent the growth, or decline, of the site.
People make puzzles with different numbers of words. The following shows the size puzzles people make over the last two months.
The next graph is not particularly informative. This attempts to show repeat activity. As expected, most IP addresses only create a few (less then 30 or so) puzzles. There are only so many puzzles that a person can create. At the right of the graph, there are a few IP addresses that visit thousands of time. But there is only one IP address with a specific count, so the data point is down on the axis. These IP addresses are proxy sites for places like aol.com.
It's not clear how to make this data meaningful with a graph.
