Adding a legend to a Chart instance
+
+When a chart has multiple series, a legend can allow the user to identify each series more easily. The charts module includes a charts-legend submodule. Specifying
+charts-legend in you use statement allows you to add a legend to a Chart instance. A legend is added to a chart through the legend attribute. This attribute is an
+object containing value pairs for the attributes of a legend. All available attributes for the legend are outlined here. In the
+example below, we will add a legend to a chart instance.
