This interactive scatter plot displays penguin measurements from a CSV dataset, allowing viewers to change both the x- and y-axes via dropdown menus while the points re-scale dynamically. Built with React and D3 v7 (including `scaleLinear`, `extent`, and `csv` for data loading), it renders as SVG circles with native `<title>` tooltips. Axis tick marks, labels, and a light grid are drawn in separate React components, with dot color fixed to dodger blue. The menus let users explore correlations among attributes like bill length, flipper length, and body mass.
