mtcars Explorer is a simple interactive Shiny app that lets users explore relationships in the famous mtcars dataset.

• Choose any two variables for a scatter plot (X and Y)
• Color points by cylinders, transmission, etc.
• Filter cars using a slider (number of cylinders)
• Toggle a regression line on/off

ggplot(mtcars, aes(x = wt, y = mpg, color = factor(cyl))) +
  geom_point(size = 5) + geom_smooth(method = "lm", se = FALSE) +
  theme_minimal()

## `geom_smooth()` using formula = 'y ~ x'

• Very intuitive for beginners
• Demonstrates reactive programming in Shiny
• Helps users discover insights (e.g., heavier cars have lower MPG)
