This example displays a bar chart of player statistics from a small dataset, with each bar representing a player's goals or age. The bars are rendered as SVG rectangles using D3 v5, with a dropdown menu to switch between the two data attributes. On mouseover, a bar highlights in orange and displays its value as text. The visualization uses D3's `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` APIs, with a transition animation on mouseout to restore the bar's original styling.
