This React-based scatter plot visualizes the Iris dataset, mapping sepal length and width for each flower specimen as circles. The chart uses D3 v6 scales and axes to position marks within an SVG, with tick marks generated via `xScale.ticks()` and rendered as SVG lines and text. React components manage the visualization’s structure, while D3’s `csv` and `scaleLinear` handle data loading and coordinate mapping. The marks include native SVG tooltips via `<title>` elements, and axis labels rotate for the y-axis.
