     Autocorrelation plot for time series.
 
+    This method generates an autocorrelation plot for a given time series,
+    which helps to identify any periodic structure or correlation within the
+    data across various lags. It shows the correlation of a time series with a
+    delayed copy of itself as a function of delay. Autocorrelation plots are useful for
+    checking randomness in a data set. If the data are random, the autocorrelations
+    should be near zero for any and all time-lag separations. If the data are not
+    random, then one or more of the autocorrelations will be significantly
+    non-zero.
