Scatter plot with D3, using the newer margin convention pattern of setting the domain of the scales relative to the SVG, rather than utilizing an additional <g> element translated by the top and left margin.

Makes use of Rollup so that we can author the code using ES modules.

Inspired by the patterns found in Observable: D3 Charts.

I personally prefer the old margin convention, because it's simpler to reason about (you can isolate the thinking around innerWidth and innerHeight, rather than always considering margin.top, margin.right, margin.bottom, and margin.left).
