This took way longer than it should have for me to get working. Based on [@connor-roche/multi-line-chart-focus-context](https://observablehq.com/@connor-roche/multi-line-chart-focus-context) but modified to use the `data` object pattern from [@d3/multi-line-chart](https://observablehq.com/@d3/multi-line-chart)
