This scatter plot visualizes the iris dataset, showing sepal length against petal length for three flower species, with each species represented by a distinct D3 symbol shape. The visualization is built using D3 v7, employing scaleLinear for axis scales, scaleOrdinal with symbolsFill for shape encoding, and a custom shape legend component. The plot loads data from a CSV file, converts numeric string fields to numbers, and renders the chart across the full browser viewport with labeled axes for sepal and petal length.
