This interactive scatter plot displays the classic Iris dataset, letting users explore relationships between sepal and petal measurements. Two dropdown menus allow switching the x-axis and y-axis variables, while the scatter points update dynamically. The visualization uses React with hooks for state management, D3 v5 scales and SVG rendering for circles and axes. Data loads from a CSV via d3.csv, with axes formatted using d3.format and annotated with rotated axis labels.
