This scatter plot visualizes penguin measurements, mapping flipper length to bill length on the x-axis and body mass to bill depth on the y-axis, with circle sizes representing bill dimensions and colors indicating species (Adelie, Gentoo, or Chinstrap). It uses D3 v5 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load and scale the data from a GitHub-hosted CSV, rendering SVG circles with custom labels and a cursive font.
