This fork of a D3 scatter plot visualizes the Iris Dataset, mapping petal length on the x-axis and sepal length on the y-axis using d3.scaleLinear with nice tick values. It loads CSV data via d3.csv, parses numeric fields, and renders circles with SVG attributes set through d3.select and data joins. The visualization fills the browser window, adding an axisBottom and axisRight using d3.axisBottom and d3.axisRight, with a 24-pixel tick font size and fixed margins around the plot.
