This example shows a scatter plot of penguin species, mapping flipper length to the x-axis and body mass to the y-axis, with each point colored by species (Adelie, Gentoo, or Chinstrap). The visualization loads data from a remote CSV, parses numeric fields, and renders circles using D3 v5’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs onto an SVG canvas. The chart includes labeled axes and a title, with axis text styled in cursive.
