Weekly Attendance - Aggregate Count Only

This chart contains no student names - only weekly totals.

What This Shows

The dip at week 9 is the school break week, not a drop in engagement. Attendance recovers immediately afterwards.
Everything a club leader needs from attendance data - the trend, the dip, the recovery, the year-over-year comparison - is visible here, and none of it requires a single student's name. Aggregate reporting is not a compromise; for this question it is sufficient.
