This animated scatter plot displays phone data, alternating the x-axis between Price and SalesVolume every two seconds to reveal different relationships in the dataset. Built with D3.js v7, it uses SVG circles with a fixed radius and steelblue fill, positioned via linear scales derived from the CSV data. The chart is constructed through a custom `createScatterPlot` function that leverages D3's `selectAll` and `join` for efficient DOM updates, while `setInterval` drives the periodic column switching animation.
