--description--

The range for this scale will go from the left of your graph to the right, with 2012 on the left and 2020 on the right. Add the range function to the xScale and pass it an array with the values: svgMargin and svgWidth - svgMargin. This will translate to [70, 630]. So 2012 will use 70 as is x-coordinate and 2020 will use 630 as its x-coordinate.

const range = xScale.range();
assert(range.length === 2 && range[0] === 70 && range[1] === 630);
