This interactive scatter plot displays the classic Iris dataset, allowing users to explore relationships between four measured attributes (sepal and petal length and width). Two dropdown menus control which numeric attributes are mapped to the x and y axes, dynamically updating the visualization. Color is not used for encoding; all points are rendered as teal circles. The visualization uses React for the interface and D3.js for data loading and scale computation (d3.csv, d3.scaleLinear, d3.extent, d3.format). SVG circles are mapped to data points, with mouse-over tooltips showing the exact x-axis value. The data is loaded client-side from a CSV file.
