This depends on the, Speedy Time Tracker shortcut. Once generated there will be a graph.html file in the /ShortCuts/SpeedyTimeTracker/ directory in iCloud. iOS and padOS devices will not be able to display it with Safari or Chrome but there are other tools like Working Copy, Coda, and other HTML editors that will display it or you can load it on your MacOS device easily.

The graph uses Google Graph API to generate a timeline graph, each line being a day of the week.
