This scatterplot shows the relationship between flipper length and bill length for penguins, with each point colored by species. The visualization uses D3 v7 scales (`d3.scaleLinear` for axes and `d3.scaleOrdinal` with `d3.schemeCategory10` for colors) and renders circles as SVG marks. Data comes from the Penguins.csv file, loaded via `d3.csv`. The circle radius is also mapped to flipper length, while labeled axes for flipper and bill length are generated with `d3.axisBottom` and `d3.axisLeft`.
