This scatter plot visualizes Iris flower measurements, mapping sepal length to the x-axis and petal length to the y-axis, with species encoded by distinct shapes. The chart uses d3.scaleLinear for position scales and d3.scaleOrdinal with d3.symbolsFill to assign geometric symbols to each species. A custom shape legend explains the species-to-symbol mapping, while d3.axisLeft and d3.axisBottom render the labeled axes. Data is loaded from a remote CSV and parsed with d3.csvParse before being plotted.
