This interactive scatter plot visualizes the Iris dataset, cycling through different variable pairings every two seconds. The visualization uses a reusable D3 chart module, with `scaleLinear` for axes, `scaleOrdinal` for categorical coloring by species, and `axisLeft`/`axisBottom` for ticks. Data is loaded via `d3.csv` from a GitHub Gist, rendered as SVG circles, and includes a legend. The chart demonstrates a modular approach to building configurable, animated D3 visualizations.
