This scatter plot displays the classic Iris dataset, showing sepal length and sepal width for three flower species, with each species color-coded (blue, red, green) as points on an SVG canvas. The visualization is built with D3 v5, using `scaleLinear` for axes, `axisBottom` and `axisLeft` for grid lines, and `csv` to load the data from a local file. The code calculates the value ranges dynamically with `extent` and applies `.nice()` for axis scaling, while circle opacity is set globally via CSS.
