This interactive scatter chart displays the Iris flower dataset, plotting sepal length against sepal width using React components for rendering and D3.js scales for positioning. The visualization includes dropdown menus for selecting different data attributes, along with axis labels and tick marks generated from D3’s scaleLinear and extent functions. SVG circles represent individual data points, with tooltips showing formatted values. The chart loads CSV data asynchronously through a custom `useData` hook that parses numeric fields.
