This fork of the Penguin Dataset scatter plot visualizes flipper length against body mass, with points colored by penguin species and scaled by culmen dimensions. The code loads data via `d3.csv`, parses numeric fields, and renders an SVG using `d3.select`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`. Circles are positioned with `cx` and `cy`, colored by a species-based marker function, and styled with radius, `rx`, and `ry` attributes. The chart includes labeled axes and a title, sized to the window.
