About the Dataset

We use the built-in mtcars dataset.

Variables shown in the plot:

• mpg = Miles per gallon
• cyl = Number of cylinders

The bubble colors represent different cylinder groups.

Interactive Plot

Key Observations

The interactive chart shows that:

• Heavier cars generally have lower fuel efficiency.
• Four-cylinder vehicles tend to achieve the highest MPG.
• Eight-cylinder vehicles are generally heavier and consume more fuel.
• Hover over each point to identify the vehicle.
