This scatter plot visualizes the Palmer Penguins dataset, showing the relationship between flipper length and body mass for three penguin species, with each species color-coded. The React application uses d3.csv to load data and d3.scaleLinear with d3.extent to map values to screen coordinates. The visualization renders circles as SVG elements with fill-opacity for overlapping points, and includes axes generated using d3.axisLeft and d3.axisBottom within a decoupled React and D3 architecture.
