This scatter plot visualizes the Iris dataset, mapping petal width against sepal length, with points colored by their attributes. Built using D3.js (v6), it employs `scaleLinear` for axes, `axisLeft` and `axisBottom` for ticks, and SVG circles for marks. The chart automatically cycles through four numeric columns—petal width, sepal width, petal length, and sepal length—on the x-axis every two seconds via `setInterval`. Data is loaded asynchronously from a CSV URL using `csv` and parsed into numbers. The reusable chart pattern, inspired by Towards Reusable Charts, accepts configurable accessor functions, with styling handled by the Share Tech font.
