This fork of the Penguin Data set scatter plot visualizes the relationship between flipper length and body mass for three penguin species, with color-coded circles distinguishing Adelie, Gentoo, and Chinstrap species. The code loads CSV data via `d3.csv`, parses numeric columns, and renders an SVG chart using `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom`. Circles are positioned with `d3.attr` for x and y coordinates, while fill colors are assigned via a custom marker function. The visualization includes labeled axes and a title, with axis text styled using cursive font.
