A group of students investigating fluvial downstream changes have measured the average clast size (longest axis in mm) and roundness score at ten systematic sample sites along a 12 km river transect. They have compiled these measurements in a data table.
Suggest one appropriate graphical or cartographical method the students could use to present this downstream clast data to show the relationship between distance from the source and clast characteristics.
