This visualization shows the Iris dataset as a scatter plot, mapping petal length on the x-axis and petal width on the y-axis, with points colored by species (setosa, versicolor, and virginica). Using D3 v6, it loads CSV data via `d3.csv`, scales the coordinates with `scaleLinear` and `extent`, and renders circles on an SVG canvas. It also includes axes via `axisLeft` and `axisBottom`, with inverted y-axis scaling and labeled axes. The code processes raw numeric fields—sepal and petal measurements—to position each data point.
