This scatter plot visualizes the Iris Dataset, plotting sepal length against sepal width for individual flowers. The React application uses D3 v7 functions like `scaleLinear`, `extent`, and `format` to build the SVG chart, with custom axis and mark components rendering tick marks and circles. The y-axis label is mistakenly assigned the x-axis label text ("Sepal Length") due to a code error, while the actual x-axis label is correctly positioned. Data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV file.
