HistogramChartSpec class

A histogram chart.

A histogram chart groups data items into bins, displaying each bin as a column of stacked items. Histograms are used to display the distribution of a dataset. Each column of items represents a range into which those items fall. The number of bins can be chosen automatically or specified explicitly.
