Each line traces a driver's lap-by-lap time across the entire race or sprint, where higher means faster. A gradual drop means tires are wearing; a sharp rise means a pit stop and fresh rubber. Dips are slow laps caused by safety cars, track incidents, or the pit stop lap itself. Lines converging means drivers are matching each other's pace; diverging means one is pulling away. Toggle Weather and Track Status to add context. A simultaneous slowdown across all drivers at the same lap usually marks a safety car or red flag.
