This interactive scatter plot visualizes the Iris dataset, displaying petal and sepal measurements as colored circles representing different species. Using D3.js version 6, the visualization cycles through four different column combinations on the x-axis every few seconds via `setInterval`, while y-axis values remain fixed. The reusable `scatterPlot` module handles axis generation with `scaleLinear`, `axisLeft`, and `axisBottom`, while the main script adds circles, a color legend, and axis labels directly to the SVG. Styled with custom CSS and Google Fonts, the animation updates smoothly without transitions.
