This scatter plot visualizes penguin measurements, mapping flipper length on the x-axis, body mass on the y-axis, and using circle color to distinguish species (Adelie, Gentoo, and Chinstrap). The code loads data from a CSV file via d3.csv, applies scales with d3.scaleLinear and d3.extent, and renders circles as SVG elements. Axis labels and ticks are generated using d3.axisLeft and d3.axisBottom, while the chart fills the full browser window. A title and cursive font styling complete the presentation.
