Histograms are graphs that display statistical data in terms of frequency. They can be thought of as tools for geovisualization for geographical studies. For example, this histogram represents the size and shape of sediments deposited after glaciation. The intervals are determined by a scale called the Cailleux Index which measures the roundness of pebbles. The most frequently occurring size of sediments from this study fell between 151 Ci and 200 Ci on this scale, while none fell between 751 Ci and 850 Ci.
