Each column is a driver, sorted fastest (left) to slowest (right). Each dot is a timed lap, lower is faster, and the shape tells you which segment it came from: circle = Q1, square = Q2, triangle = Q3. Drivers with only circles were eliminated in Q1; circles and squares made Q2 but not Q3; all three shapes means they ran in the shootout. The lowest Q3 triangle per driver is what determines their grid position.
