This example demonstrates a reusable scatter plot component built with D3.js, visualizing the Iris dataset. The plot maps petal width to the x-axis and sepal length to the y-axis, with species encoded through distinct SVG symbols. The implementation uses D3's `scaleLinear`, `scaleOrdinal`, `axisLeft`, `axisBottom`, `symbol`, and the `join` operator to create a flexible, configurable chart. The iris data is loaded from a CSV file, and the SVG rendering adapts to the full browser window dimensions.
