In this example we add a `Renderable` or a custom component to the `Elements` array.
In this specific case it is a pre-built renderable (`CreateLegend`) that draws a legend for the chart's series.
If you like, you can use `CreateLegend` as a template for writing your own renderable, or even your own legend.
