This scatter plot visualizes penguin measurements, plotting flipper length against body mass and coloring each point by species (Adelie, Gentoo, or Chinstrap). The visualization uses D3 v5’s `csv`, `scaleLinear`, `axisLeft`, and `axisBottom` APIs to load and map data from a remote CSV file, rendering circular marks with SVG. Each circle also encodes bill length and depth as its horizontal and vertical radii, creating an elliptical distortion that layers additional dimensions onto the standard scatter plot.
