Sleep Actogram

An actogram of a sleep study, 2023-2025, with synthetic data. Dot sizes indicate sleep status (awake, nap, bed, and up) every 30 minutes.

Sleep actogram showing sleep patterns from 2023 to 2025 across three color-coded years.

And the same synthetic data expressed as radial calendars.
