This scatter plot visualizes the relationship between flipper length and body mass for penguins, with each circle colored by species. It uses d3.csv to load a clean penguin dataset, d3.scaleLinear for axes, and d3.axisLeft/axisBottom to render ticks. SVG circles are positioned via scale mappings, with fill colors assigned by species. The plot includes axis labels and a title, rendered with the d3 v5 API in an SVG container sized to the window.
