A reusable D3 scatter plot displays the Iris dataset, mapping petal width against sepal length. Each circle’s color encodes the species (setosa in blue, versicolor in red, virginica in yellow), with white strokes and labeled axes. Built using `d3.csv`, `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom`, the plot updates via a configurable `scatterPlot` module, iterating through data columns. The visualization renders in SVG on a black background with white text, emphasizing interactive reuse of axes and data bindings.
