/**
 * A histogram is a chart that groups numeric data into bins, displaying the bins as segmented columns. They're used to
 * depict the distribution of a dataset: how often values fall into ranges.<br>
 * Google Charts automatically chooses the number of bins for you. All bins are equal width and have a height
 * proportional to the number of data points in the bin. In other respects, histograms are similar to column charts.
