By default uses the annotation's `bgcolor` made opaque, or white if it was transparent. If set to "paper", the `y` position refers to the distance from the bottom of the plotting area in normalized coordinates where "0" ("1") corresponds to the bottom (top). Sets the padding (in px) between the `text` and the enclosing border. We can say text are which we created on charts for annotations. Create annotations above bar plot bars. Now, a plot with different types of visuals will be made. The location of the text can also be shifted using ax=-20 and ay=-30, as an example.
