This visualization uses D3 v6 to render a scatter plot of the Iris Dataset, showing the relationship between petal length and sepal length. It employs d3.csv for data loading, d3.scaleLinear for both axes, and d3.axisLeft and d3.axisBottom to display the scales. Data points are drawn as SVG circles, with margins and a full-window responsive sizing. The dataset is fetched from a GitHub Gist, and numeric fields are parsed from strings before plotting.
