An annotation pointing to the week with the most plays

The table podcast holds the weekly plays of a podcast over 8 weeks. Draw a line chart with points, with the week (week) on the x-axis and the plays (plays) on the y-axis. Put the week with the most plays in the title, as in Plays peaked in week 4.

Add the annotation Peak: 2100 plays with an arrow pointing to the point of that week, and put the source line Source: podcast app without an arrow at the lower left in paper coordinates (xref="paper", yref="paper"). Take the numbers in the title and the annotation from the table. Show the figure with fig.show(). Grading changes the play counts and draws the chart again.

    "week": [1, 2, 3, 4, 5, 6, 7, 8],
    "plays": [1200, 1350, 1500, 2100, 1800, 1600, 1450, 1700],
