Weekly mileage vs. Marathon training plans
This visualization compares weekly training mileage for London Marathon 2016 finishers (from Strava athlete data) against four Runners World training plans targeting sub-3:00 to sub-4:30 marathons. Each panel shows a shaded area between the plan’s upper and lower mileage bounds, overlaid with the actual average finisher mileage per week. The code parses CSV data with `d3.csvParseRows`, then builds small multiples using `fc.chartCartesian`, `fc.seriesSvgArea`, `fc.seriesSvgLine`, and `fc.annotationSvgGridline` from d3fc, with scales from `d3.scaleLinear`.
