“A Summary of the WWDC26 Group Lab”

This is normal, it's expected that you need a combination of Tabs and Arrows to navigate.

Each group read like your example, for instance starts at 0.047, varies between 0.066 and 0.039, ends at 0.039, 3 values.

Representing chart data as an audio graph covers it too. In my tests it didn't reach the group
