This interactive visualization uses D3.js v7 to display World Cup team statistics from a CSV file as circles arranged in a row, with team names labeled beneath each circle. A control panel presents buttons for different data attributes such as wins, losses, points, and goals, and clicking a button uses `d3.scaleLinear` to map that attribute’s value to the circle radius via `.attr("r", ...)`. The circles initially render at a fixed size, then resize dynamically based on the selected metric, with CSS classes styling active and inactive states.
