This example presents a scatter plot of penguin data, visualizing flipper length against body mass. Each point is colored by species (Adelie, Gentoo, or Chinstrap), with additional fields for culmen length and depth stored in the data binding. The visualization uses D3 v5’s `csv` loader, `scaleLinear`, `extent`, and axis generators (`axisLeft`, `axisBottom`) to map the dataset, rendering circles as SVG elements with a fixed radius. The code also adds axis labels and a title styled with custom fonts, all within a React-compatible HTML page.
