Penguin Trait Explorer (Brushed Scatterplots)

Overview

How to Use

• Explore two scatterplots:
  • Plot 1: Bill Length vs. Bill Depth
  • Plot 2: Flipper Length vs. Body Mass

• Color = Species: Each species has its own color to distinguish groups.

• Brush to filter: Drag a rectangle on either plot to highlight points in that area. You can resize or drag the existing brush to move it. You can brush on both plots; only points inside all active brushes remain highlighted.

• Select a penguin: Click any point to view its measurements (bill, flipper, body mass, species) in the info table. The selected point enlarges in both plots.

• Move brushes to compare: Slide a brush around to see how different regions correspond across the two trait spaces.

• Reset brushes: Click on empty space (or clear the brush) to remove it and restore all points.

• Compare subsets: Use brushing to isolate a cluster (e.g., large flipper + high mass) and see where those same penguins appear in the other plot.
