This visualization compares sepal length and sepal width across three iris species. It uses a scatter plot with color-coded data points for Setosa, Versicolor, and Virginica, and includes an interactive legend that highlights matching points when hovering. The chart is rendered using D3.js with scaleLinear and scaleOrdinal APIs, and loads data from a CSV file of Fisher's Iris dataset. Point styling and legend appearance are configured through a separate config file.
