This scatter plot visualizes the Iris dataset, plotting sepal length against sepal width for individual flower samples. Each circle represents a data point, with a tooltip revealing the precise x-axis value on hover. The visualization is built with React and D3 v6, using D3's `scaleLinear` for axis scaling and `extent` to compute the data domain. SVG rendering is used for all graphical elements, including custom axis components that generate tick marks and labels. Data is loaded asynchronously as CSV from a remote URL using D3's `csv` function.
