An SVG Line chart using transparency

This is a Line chart that has some custom values applied to it. It's a filled chart, also using the filledAccumulative option too ao the datasets are stacked one or top of the other. Gradients have been given to the fills and different colours given to the strokes. It's also using the trace effect.

The gradients that are used as the fills aren't used for the strokeStyles of the lines - those are separate green and blue (they aren't set specifically - rather using the defaults instead.

There's a canvas version of this chart where the datasets are traced indiviually and sequentially.
