This visualization displays the classic Iris dataset as a scatterplot, mapping sepal length on the x-axis and sepal width on the y-axis, with each of the three species colored distinctly (red, green, blue). The code loads data from a CSV via `d3.csv`, uses linear scales (`d3.scaleLinear`) to map data coordinates, and renders circles (`svg.selectAll("circle")`) using the SVG rendering approach. Axes are constructed with `d3.axisBottom` and `d3.axisLeft` within a D3 v7 React-free HTML page.
