This reusable D3 scatter plot animates through different iris flower measurements, cycling the x-axis column every two seconds. Built with a chainable `scatterPlot` function using `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom`, it renders SVG circles and axes from a CSV dataset fetched via `d3.csv`. The code demonstrates dynamic updates by re-invoking the plot with new `xValue` accessors, showing how a component can be reconfigured and reused across data dimensions.
