This fork of a scatterplot visualizes penguin body measurements from a world dataset. It plots flipper length on the x-axis and body mass on the y-axis, with each point colored by penguin species. The code uses D3 v6 functions including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`, rendering SVG circles with mouseover event logging. The chart displays axes, labels, and a title using SVG text elements.
