This interactive scatterplot visualizes the Palmer Archipelago penguin dataset, plotting body mass against bill length, then automatically cycles through other numerical attributes every two seconds. Built with D3.js, it uses a reusable `scatterPlot` component that binds scales, axes, and circles, updating the plot via a `setInterval` loop. The SVG rendering, styled with the Share Tech font, smoothly transitions the x-axis and data points as the selected column changes, demonstrating a flexible, variable-driven plotting approach.
