This interactive scatter plot visualizes the relationship between flipper length and body mass for three penguin species, with each point colored by species. Built using D3 v5 within a React starter template, the visualization loads CSV data and uses `d3.scaleLinear` with `d3.extent` to map coordinates, rendering SVG circles. The chart includes `d3.axisLeft` and `d3.axisBottom` axes, along with descriptive labels for both dimensions.
