This interactive scatter plot displays the Iris dataset, mapping petal width against sepal length and coloring each point by species. The visualization is built using D3.js v6, with `scaleLinear` for axes, `axisLeft`/`axisBottom` for ticks, and a reusable `scatterPlot` function that accepts configurable width, height, margins, and data accessors. Circles are joined via `selection.join`, with species-based color coding (red, green, blue). The plot renders in SVG, initially showing petal width on the x-axis, which then switches to sepal width for the final view.
