Description
It’d be nice if you could say
Plot.rectY(athletes, Plot.binX({y: "percent"}, {x: "weight"})).plot()
and it would be equivalent to
Plot.rectY(athletes, Plot.binX({y: "proportion"}, {x: "weight"})).plot({y: {percent: true}})

Research direction
Start by tracing the Plot.binX reducer path and how the existing "proportion" reducer is transformed by the plot y percent option. Implement the requested "percent" behavior so the first example is equivalent to the second, then verify the resulting chart values against that equivalence.
