Aggregate data is not considered personal data by the GDPR.
Managers and everyone else can have charts and graphs without retaining personal data.
The processing of personal data prior to anonymisation to turn it into aggregate data, that part needs protection. But you can do it in a variety of ways that don't require personally invasive tracking.
