Milestones and phases, binding a timeline to a table, and its styling. A chart answers "how much"; a timeline answers "when". Insert one on a sheet from Reports → Timeline, or on a dashboard from Dashboard → Add Widget → Timeline. It arrives as a worked example — kick-off, two phases, pilot, go-live — so it is a picture immediately; replace those in the settings panel. A MILESTONE is a point in time with a marker (circle, diamond, square, triangle, star, flag, pin, or none) and a label; a PHASE is the same thing with an end date, drawn as a bar.
