This scatter plot visualizes the relationship between sepal length and sepal width in the classic Iris dataset, using purple semi-transparent points. The visualization is built with D3.js v7, loading data from a remote CSV via `d3.csv` and rendering to an SVG canvas. The code utilizes `d3.scaleLinear` with `d3.extent` for axis scaling, positions circles with `cx` and `cy` attributes, and adds labeled axes and a title through `d3.axisBottom` and `d3.axisLeft`.
