This chart displays the relationship between sepal length and petal length for 100 iris flower samples, with each dot colored by species using a Tableau10 ordinal color scale. It reads the dataset from a CSV file using `d3.csv` and renders points as circles in an SVG canvas. The visualization includes axes, tick marks, and labels, and features interactive tooltips that appear on mouseover events. D3's extent and scaleLinear functions manage the continuous data mapping for both axes.
