This interactive scatter plot visualizes the Iris dataset, cycling through different feature combinations on the x-axis every few seconds with animated transitions. The chart uses D3.js (v6) within a React framework, rendering SVG circles colored by species (setosa, versicolor, virginica) with a custom legend and axis labels. The code leverages `scaleLinear`, `axisBottom`, `axisLeft`, and `setInterval` to dynamically update the visualization, pulling data from a CSV via `d3.csv`. A custom reusable scatter plot module manages the chart’s core structure and rendering.
