This scatter plot visualizes the Iris Dataset, plotting sepal length against petal length for 150 flower samples. The visualization loads data from a CSV file using `fetch` and `csvParse`, then renders circles with `selectAll` and `join`. D3 v7 scales (`scaleLinear`, `extent`) map data values to screen coordinates. Reusable axis components (`axisLeft`, `axisBottom`) display labeled x and y axes with offsets for the axis titles.
