+
+`HorizontalBarChart` charts take Date, Number or String data types for the Y-Axis and Number data types for the X-Axis. For the Y-Axis, each category is given its own tick mark.
+
+It supports `labels` and `tooltips`, but more advanced features like `error bars` or `stacking` are not yet implemented.
+
+Series render style is `Bar`.
