This interactive scatter plot visualizes the Iris dataset, with the x-axis cycling through different flower measurements every two seconds while the y-axis remains fixed to sepal length. The visualization uses D3 v6 APIs including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`, along with SVG circle marks and animated transitions via `setInterval`. The axis scales recalculate when the selected column changes, smoothly updating the points and tick marks to reveal correlations between different iris features.
