A happier histogram plot

The stock exchange firm you created the histogram for thinks that all the data and plots being created are too impersonal.

They have requested that a positive message be added to the histogram plot of company revenues you recently created.

You have just the right idea - you can wish the viewer a happy day and use the current day of the week for this!

There is a fig histogram available for you, feel free to show() or print() it to remind yourself what it looks like.

Position the annotation halfway along the x-axis and 95% up the y-axis.
Set the correct values for xref and yref to allow for relative positioning.
Use the provided today variable in the text, setting the font size to 20 and text color to 'white'.
Use the update_layout() method to add the annotation.
