This interactive scatter plot explores the Iris dataset, cycling through different feature pairings on the x-axis while keeping sepal length on the y-axis. D3's `csv` loader ingests remote data, with points colored by species. Animated via `setInterval`, the visualization updates the x-axis mapping and redraws the chart using a custom `scatterPlot` builder that leverages D3's `scaleLinear`, `axisLeft`, and `axisBottom`. SVG rendering with embedded legends and titles provides a clear, self-contained exploration of the data's multivariate relationships.
