This visualization displays the Iris Dataset as a scatter plot, mapping petal length on the x-axis and sepal length on the y-axis. Each flower is represented by a small circle, with axes generated using `d3.axisLeft` and `d3.axisBottom`. The code loads CSV data via `d3.csv`, parses numeric columns, and applies `d3.scaleLinear` with `d3.extent` to set the scales. The SVG chart resizes to the full browser window, and circles are rendered using `d3.selectAll` with a `.join()` pattern.
