This example renders the classic Iris dataset as a reusable scatter plot in D3 v6. It uses d3.scaleLinear and d3.axisBottom/axisLeft to map petal width against sepal length, with d3.scaleOrdinal assigning distinct colors and SVG symbol shapes by species. The chart updates every 10 seconds, cycling through different x-axis columns via setInterval, demonstrating dynamic axis transitions. Data is loaded asynchronously from a CSV URL using d3.csv.
