This dynamic scatter plot visualizes the Iris Dataset, mapping petal width against sepal length while encoding the three iris species with distinct D3 symbol shapes. The visualization uses `d3.scaleLinear` and `d3.scaleOrdinal` to position points and assign symbols, with `d3.axisLeft` and `d3.axisBottom` providing labeled axes. Each data point renders as an SVG path generated by the `d3.symbol` generator, sized at 100 pixels squared, and the chart updates transparently when the dataset or encoding functions change through its reusable `scatterPlot` module.
