This scatterplot visualizes the relationship between flipper length and body mass for penguins, revealing a positive correlation between the two measurements. The visualization uses d3.csv to load the penguins dataset from the seaborn-data GitHub repository, filtering out entries with missing values before plotting. D3 v7 scales map the data to SVG coordinates, with d3.axisBottom and d3.axisLeft generating the labeled axes, while steelblue circles at radius 4 mark each penguin observation.
