This animated scatter plot explores the Iris flower dataset, cycling through different feature pairings on the x-axis to reveal relationships between sepal and petal measurements. Points are colored by species (setosa, versicolor, virginica) and positioned using D3.js scales and axes from the `d3` library. The visualization updates every few seconds, re-rendering the plot with a new attribute on the horizontal axis while keeping the vertical axis fixed, allowing comparison across dimensions. The code uses D3’s `csv` loader, `scaleLinear`, `axisLeft`, and `axisBottom` to construct the reusable scatter plot, with an SVG canvas and custom legend.
