The Olympic Swimming Project visualization displays a bar chart showing the count of gold medal winners by country for the 100m freestyle event, with each bar colored distinctly. It processes Tokyo 2020 swimming data from a CSV file, filtering for rank 1 results, then aggregates and ranks the top ten countries. The chart is created using D3's scaleBand for the categorical x-axis, scaleLinear for the numeric y-axis, and scaleOrdinal for bar coloring, with axis labels added via the @curran/axis-labels library. The visualization highlights national dominance in a specific swimming discipline through an accessible, color-coded bar format.
