This interactive scatterplot explorer visualizes the Iris flower dataset, allowing users to select which quantitative attributes to plot on the X and Y axes via dropdown menus. The visualization dynamically determines the appropriate statistical test (e.g., t-test, ANOVA, chi-squared) based on the data types of the selected variables, displaying the test type as a header. Built with React and D3 v7, the SVG rendering uses `scaleLinear` and `extent` for axis scaling, while data classification and parsing are handled through custom logic in `useData.js` using `csv` loading.
