This scatter plot visualizes the classic Iris dataset, displaying sepal length on the x-axis and sepal width on the y-axis for 150 flower samples. Each circle represents an individual iris, rendered with an opacity of 0.5 using D3’s `scaleLinear` and `extent` to map data values to screen coordinates within a fixed margin. The visualization loads CSV data via `d3.csv`, converts numeric fields, and appends SVG circles to the document body, filling the full window size with a 10-pixel radius per point.
