Swarm Plot
A swarm plot visualizes the transfer fees of football players, grouped by their position on the pitch. The data, sourced from a CSV file, shows each player as a circle colored by position, with the vertical axis mapping the fee in millions. This implementation uses D3 v5 to load the data and render SVG circles, with an ordinal scale for horizontal positioning and a linear scale for the vertical fee axis. The code assigns colors using `d3.scaleOrdinal` with the `schemePaired` color palette.
