This reusable scatter plot, built with D3.js, visualizes the Iris dataset, mapping petal width to the x-axis and sepal length to the y-axis while encoding species with different symbols. The chart updates every 15 seconds, cycling through the four numeric columns for the x-axis. It uses a modular `scatterPlot` function with D3 scales, ordinal symbols, and axes, rendered as SVG, based on the "Towards Reusable Charts" pattern.
