This scatter plot visualizes the relationship between sepal length and petal length for different iris species, using distinct symbols to differentiate each species. The visualization is built with D3 v7, employing `scaleLinear` for the axes, `scaleOrdinal` and `symbolsFill` to assign shapes, and `symbol` to render the data points. A legend, created via `shapeLegend`, maps each species to its corresponding symbol. The data is loaded from a CSV file and rendered using the `scatterPlot` and `axes` functions.
