This fork of a reusable D3 scatterplot visualizes the Iris dataset, encoding sepal length and petal width with positions onto an SVG canvas while symbol shapes and colors both map to the species category. The code builds custom plot margins and axes using `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom`. It demonstrates a reusable chart pattern in React, where the scatter plot component exposes setter methods for dimensions, data accessors, and margins. Data is loaded asynchronously via `d3.csv` and parsed into numeric values before rendering.
