This visualization displays the Iris dataset as a scatter plot, mapping petal length on the x-axis and petal width on the y-axis. Each circle represents an iris flower, colored by species (blue for setosa, yellow for versicolor, green for virginica) using D3 v6 APIs including `csv`, `scaleLinear`, `extent`, and `axisBottom`. The SVG renders circles with a fixed radius, while sepal measurements are bound but not visually encoded. Data is loaded from a GitHub gist via CSV, with axes labeled and styled via CSS.
