This visualization uses a bar chart to show the percentage of points Rafael Nadal won under pressure across seven clay-court tournaments, including Monte Carlo, Rome, Barcelona, Buenos Aires, Roland Garros, Sao Paulo, and Madrid. The bars are colored with a sequential quantized scale (`d3.scaleQuantize`) ranging from light to dark red, and a legend from the d3-legend library indicates the percent values. The chart is rendered with SVG using D3 v7’s `d3.scaleBand` and `d3.axisBottom`/`d3.axisLeft`, with data loaded from a CSV file hosted on GitHub.
