This scatter plot visualizes the Iris dataset, showing petal length against sepal width and coloring each point by species. The visualization includes axes, tick marks, a species color legend with circular swatches, and hover tooltips displaying formatted x-values. Built with React and D3 v5, it uses `scaleLinear` for positional encoding, `scaleOrdinal` for categorical colors, and `csv` for data loading. The SVG rendering includes custom axis components and circular marks, with the legend positioned to the right of the plot area.
