This interactive scatter plot, built with D3, displays the Iris dataset and animates a cycle through different feature combinations on the x-axis while the y-axis remains fixed. The visualization uses a reusable chart API, defining a `scatterPlot` function with methods for width, height, data, and margin, and leverages D3's `scaleLinear`, `axisLeft`, and `axisBottom` for rendering. The animation is driven by `setInterval`, updating the x-value every two seconds, and the plot is rendered as an SVG with a custom font loaded from Google Fonts.
