This example displays a scatter plot of penguin measurements, showing flipper length on the x-axis and body mass on the y-axis. Each circle is colored by penguin species, and the D3.js v5 code loads a CSV dataset from a GitHub gist using the `d3.csv` function. The visualization uses SVG rendering with `d3.scaleLinear` for axes, and it includes axis labels and a title. The plot is responsive, filling the entire browser window.
