This scatter plot visualizes iris flower measurements, comparing sepal length against petal length with each species represented by a distinct symbol shape. The visualization uses D3 v7’s scaleLinear, scaleOrdinal, and symbol generators to map data points and render the shape legend. Axes are drawn with axisLeft and axisBottom, while labels are positioned manually. Data is loaded asynchronously from a CSV file using d3.csvParse and fetched from a remote URL, with numerical fields converted before rendering.
