This interactive scatter plot visualizes the Iris dataset, mapping petal length on the x-axis against petal width on the y-axis, with each point colored by species and accompanied by a legend. Built as a reusable D3 module, it uses `d3.csv` for data loading, `scaleLinear` and `scaleOrdinal` for scales, and `axisBottom` and `axisLeft` for axes. The chart renders as an SVG, filling the browser window, and includes a styled title and axis labels.
