A scatter plot shows the relationship between bill length and flipper length for penguins, with each circle representing an individual observation. The data loads from a GitHub-hosted CSV file via d3.csv and renders as a static SVG. The visualization uses d3.scaleLinear for both axes, d3.axisLeft for the y-axis, and the @curran/axis-labels library for axis titles. A light gray inner rectangle delineates the plotting area, while semi-transparent circles reveal overlapping points.
