This scatter plot visualizes relationships among penguin measurements, with flipper length on the x-axis, body mass on the y-axis, and points colored by species (Adelie, Gentoo, or Chinstrap). The code loads CSV data from a GitHub gist, parses numeric fields, and scales axes using d3.scaleLinear and d3.extent. It renders SVG circles via d3.select, data joins, and join methods, with axes generated by d3.axisLeft and d3.axisBottom. Axis labels and a title are appended as SVG text elements, styled with cursive and times fonts.
