This example shows the top 20 sports clubs by revenue, combining purple bars for revenue (USD Millions) on a left y-axis with an orange line and points for championships won on a right y-axis. Club names run along the rotated bottom x-axis. The visualization uses React with D3 v5’s `scaleBand`, `scaleLinear`, `line`, and axis functions for SVG rendering. Data is loaded from a CSV via `csv`, filtered to remove missing values, and sorted by revenue before display.
