A Box Plot is a simple geovisualization tool that shows the summary of a set of data. This is simplistic in that it highlights four key points: the average, the median, and the 'measures of dispersion;' that is, the highest and the lowest of the data collected. This particular box plot graphed the annual snow depth for a fictional ski resort using a five figure summary (the numbers previously mentioned that where needed to create a box plot), that is, the lowest depth in centimeters and the highest depth in centimeters, the halfway point between the lowest and the median, and the halfway point between the median and the highest. The range at the bottom shows begins at 0 cm of snow and ends up at 140 cm of snow.
