This example demonstrates a reusable scatter plot of the Iris dataset, cycling through different flower measurements every two seconds. Built with D3 and React, it uses `scaleLinear`, `axisLeft`, and `axisBottom` to render SVG circles colored by species. The chart updates dynamically via `setInterval`, calling the plot’s accessor methods like `xValue()` and `yValue()` to re-bind data, while `join()` handles enter/update/exit transitions. Data loads from a CSV URL using `d3.csv` with parsed numeric columns, and margins, radius, and species accessors are configurable through a fluent API.
