This scatter plot visualizes penguin data, mapping flipper length on the x-axis and body mass on the y-axis, with each circle colored by species (Adelie, Gentoo, or other). The visualization uses D3 v5 and React, rendering with SVG. It loads CSV data via `d3.csv`, applies `scaleLinear` and `extent` for axes, and draws circles with `data.join`. Axis labels and a title are added using D3’s `axisLeft`, `axisBottom`, and text elements.
