This bar chart displays the total revenue, in millions of dollars, of the world’s top 10 highest-earning athletes, with each bar labeled by the athlete’s name along the vertical axis. The visualization uses React to render an SVG and D3’s `scaleBand`, `scaleLinear`, and `csv` to load and map the data from a remote CSV file. Axes are custom-drawn using D3’s `ticks()` method, with manual positioning of tick labels and lines, while the chart itself highlights red bars with blue text and a red axis grid.
