+        Grouped bar charts visualize a collection of categorical datasets. Each value
+        in a dataset belongs to a distinct category and these categories are the same
+        across all datasets. The categories typically have string names, but could
+        also be dates or index keys. The values in each dataset are represented by a
+        sequence of bars of the same color. The bars of all datasets are grouped
+        together by their shared categories. The category names are drawn as the tick
+        labels for each bar group. Each dataset has a distinct bar color, and can
+        optionally get a label that is used for the legend.
