This scatter plot displays the relationship between sepal length and petal length for three Iris species, using distinct symbols (circle, cross, diamond) and colors to encode the species categories. The visualization, built with D3 v7, uses `scaleOrdinal` for species mapping, `scaleLinear` for axes, and SVG `path` elements for the custom symbol shapes. Data is loaded asynchronously from a remote CSV file, with the legend positioned at a fixed coordinate to identify the species. The chart leverages D3's declarative join operator for efficient DOM updates and includes axis labels for both measurements.
