This scatter plot visualizes the sepal length and sepal width of iris flowers from a CSV dataset. It uses the D3.js `scaleLinear` API to map the data’s extent to the SVG canvas, with axes and tick marks generated by custom React components. Circle marks are positioned using `xScale` and `yScale`, and each includes a `<title>` tooltip. The visualization is rendered with React and D3 v5, using SVG elements and Oswald font styling.
