* Reproduce the first figure (sequence plot)
```{r}
plot(data_set,
     type = "l",          # "l" for line plot (use "p" for points, "b" for both)
     main = "Values of Data Set Over Index", # Title of the plot
     xlab = "Index",      # Label for the x-axis
     ylab = "Value",      # Label for the y-axis
     col = "blue",        # Color of the line
     lwd = 2              # Line width
)
```
#+RESULTS:

* Reproduce the second figure (histogram)
```{r}
hist(data_set,
     main = "Distribution of Data Set Values", # Title
     xlab = "Value",                            # X-axis label
     ylab = "Frequency",                        # Y-axis label
     col = "lightblue",                         # Bar color
     border = "black"  ,                        # Border color for bars
     breaks = 5 # Suggest approximately 10 bins
)
