This scatter plot visualizes the Iris dataset, showing the relationship between sepal length and petal length. Each circle represents a flower specimen, colored by species using `d3.scaleOrdinal` with `d3.schemeCategory10`. The visualization uses `d3.axisBottom` and `d3.axisLeft` for axes, with labels for both dimensions and a categorical color legend. Data is loaded from a CSV URL and parsed with `d3.csv`, while the SVG rendering includes custom margins and axis styling.
