fig, ax = plt.subplots(subplot_kw={'projection': 'polar'})
ax.plot(theta, r)
ax.set_rticks([0.5, 1, 1.5, 2])
ax.grid(True)
plt.show()

Summary Statistics (R)

Using base R to summarize the cars dataset:

Code
summary(cars)

     speed           dist       
 Min.   : 4.0   Min.   :  2.00  
 1st Qu.:12.0   1st Qu.: 26.00  
 Median :15.0   Median : 36.00  
 Mean   :15.4   Mean   : 42.98

Histogram in R

A basic histogram using base R:

Code
hist(cars$speed, col = "skyblue", main = "Histogram of Speed", xlab = "Speed (mph)")

ggplot2 Chart (R)

A modern histogram using ggplot2:

Code
library(ggplot2)

ggplot(cars, aes(x = speed)) +
  geom_histogram(binwidth = 2, fill = "tomato", color = "white") +
  labs(title = "Speed Distribution (ggplot2)", x = "Speed", y = "Count") +
  theme_minimal()
