Can we have better way to look at the Recovery Dashboard?

At present the single line chart doesn't convey a lot. Is there a possibility of showing this as a heatmap of sorts? Each day colour coded either red,yellow,green which would clearly show days where recovery has been good/meh/ugly? Or if we want to persist with a line chart, the background is split into Green, Yellow, Red and the data points change colour based on where they are at?
