ggplot(mtcars, aes(x = wt, y = mpg, color = factor(cyl))) +
  geom_point(size = 3) +
  labs(
    title = "Miles per Gallon vs Weight",
    subtitle = "Colored by number of cylinders",
    x = "Weight (1000 lbs)",
    y = "Miles per Gallon",
    color = "Cylinders"
  ) +
  theme_more_light_01()

# Customized version with white background
ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) +

  labs(
    title = "Iris Dataset: Sepal Dimensions",
    subtitle = "Length vs Width by Species"
  ) +
  theme_more_light_01(
    base_size = 14,

    grid_color = "grey85",
    show_grid_minor = TRUE
  )

Using theme_more_light_02

# Clean minimal style with light gray background

# Bar chart with the minimal theme
ggplot(mtcars, aes(x = factor(cyl), fill = factor(cyl))) +
  geom_bar() +
