This scatter plot visualizes the Iris dataset, mapping petal length and sepal width along the x and y axes while coloring each point by species. The visualization includes an interactive color legend on the right side, allowing viewers to distinguish between the three iris species. Built with React and D3 v5, the chart uses d3.scaleLinear for the axes and d3.scaleOrdinal for color encoding. Native SVG elements render the circles and legend, with d3.csv loading the dataset and reusable components managing axis and mark rendering.
