This scatter plot visualizes the Palmer Penguins dataset, showing flipper length on the x-axis against body mass on the y-axis, with each point colored by species (green for Adelie, blue for Chinstrap, gray for Gentoo). The visualization uses D3 v6’s `scaleLinear`, `axisLeft`, and `axisBottom` to map scales and render axes within an SVG. Data is loaded asynchronously via `d3.csv` from a GitHub gist, with numeric fields parsed on ingestion. Point positions are computed using the `extent` function for domain scaling, and circles are joined to the SVG using `selectAll` and `join`.
