This interactive scatter plot displays the Iris dataset, encoding sepal and petal measurements as x and y coordinates. Points are differentiated by species using both color (via `d3.scaleOrdinal` with `schemeCategory10`) and shape (via `d3.symbol` with distinct symbol types). Every ten seconds, the x-axis automatically switches among four measurement columns—petal width, sepal width, petal length, and sepal length—updating the chart through a custom `scatterPlot` function. The SVG is rendered with D3 v6, using `csv` to load data and `axisLeft` and `axisBottom` for dynamic axes.
