Introduction to the Dataset

  • This presentation leverages the mtcars dataset from the base R datasets package.
  • We will explore the interactive relationship between:
    • Gross Horsepower (hp)
    • Miles Per Gallon (mpg)
    • Number of Cylinders (cyl)
  • Use your mouse to hover, zoom, and pan across the interactive graph on the next slide!

Summary & Key Takeaways

  • Negative Correlation: As gross horsepower increases, miles per gallon (mpg) drops significantly.
  • Cylinder Clustering:
    • 4-cylinder cars occupy the high-efficiency, lower-horsepower tier.
    • 8-cylinder vehicles cluster around high-horsepower, lower-efficiency performance.
  • Interactive Tooltip: Hovering highlights specific weight vectors and unique car model text seamlessly.
