This interactive scatter plot visualizes the Iris dataset, showing how sepal and petal measurements separate three flower species. Users select which features appear on each axis via button panels, dynamically updating the visualization. The plot is rendered as an SVG using D3.js v5, with scales created via `scaleLinear`, axes via `axisLeft` and `axisBottom`, and species drawn as semi-transparent circles in distinct colors. Data originates from the included `iris.csv` file.
