This fork of the Iris Dataset scatter plot visualizes petal length and width for three iris species, coloring each point by species (blue, red, or black). The D3 v6 code loads CSV data from a gist, maps petal dimensions to the x and y axes, and draws circles with a fixed radius of 5 pixels. It uses `d3.csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render the chart, while also extracting sepal length and width values (rx and ry) without affecting the plot’s visual output.
