This interactive scatter plot visualizes the Iris dataset, cycling through different feature pairings on the x-axis every few seconds. Points are color-coded by species (setosa, versicolor, and virginica), with a legend and axis labels updating dynamically. Built with D3 v6 and React, the visualization uses `d3.csv` to load data, `scaleLinear` and `axisBottom`/`axisLeft` for scales and axes, and `setInterval` to animate transitions between sepal and petal measurements. SVG circles render the data, while CSS styling applies a custom font.
