This dashboard visualizes the performance of individual skiers across multiple runs, comparing their race time ratios against a reference time. A dropdown menu lets users select a start number (BIB) to view that skier’s data. The chart uses D3 v6 to render an SVG bar chart, with red bars for positive ratios and teal bars for negative ones, and D3 scales and axes for layout. Data is loaded from a CSV file and filtered dynamically upon selection.
