This interactive scatter plot visualizes the Iris dataset, cycling every two seconds between four flower measurements (petal width, sepal width, petal length, and sepal length) on the x-axis while sepal length remains on the y-axis. Built with D3 v6, it uses `scaleLinear`, `axisLeft`, and `axisBottom` to render axes, and `selectAll` with `join` to update circles smoothly. The reusable `scatterPlot` function, inspired by Mike Bostock's chart conventions, accepts configurable accessors for data, dimensions, and margins. Data loads from a CSV via `d3.csv`, and the animation uses `setInterval` to re-invoke the plot with new column mappings.
