This bubble chart visualizes the relationship between sports' popularity, participation, and revenue, where each circle represents a sport, with its x-position mapped to participation and y-position to popularity, while the circle radius encodes revenue. The color distinguishes each sport. Built with D3 v6, the visualization uses `d3.scaleLinear` for axis and radius scaling, `d3.scaleOrdinal` with `schemeCategory10` for colors, and SVG circles. Interactive tooltips appear on mouseover, displaying the sport's values. Axes, labels, and bottom/left axis ticks are generated via `d3.axisBottom` and `d3.axisLeft`.
