This fork of a D3 scatter plot visualizes the Iris dataset, plotting petal length on the x-axis against sepal length on the y-axis. Each flower observation appears as a circle, with scales computed from the data’s extent using `d3.scaleLinear` and `d3.extent`. The visualization loads CSV data via `d3.csv`, renders SVG circles with `selectAll` and `join`, and adds axes using `d3.axisLeft` and `d3.axisBottom`. The chart fills the browser window, with margins offsetting the axes and a fixed point radius of five pixels.
