This scatter plot visualizes the relationship between sepal length and petal length for three Iris flower species, using the classic Iris dataset. Each flower is represented as a colored circle, with species distinctions shown through a categorical color scale. The visualization is built with D3 v7, using `d3.csv` to load the data, `d3.scaleLinear` for the x and y axes, and SVG for rendering. A legend identifies species, and the plot includes clear axis labels and a title.
