make_line_chart(months, revenue) that creates a figure, draws revenue over months as a line, and returns the axes.
Example. fig, ax = plt.subplots() gives you a figure and axes; the line goes on the axes.
Notes. Return ax, not fig. One line only — don't add extra plots.make_bar_chart(categories, sales) that draws one bar per category with its sales as the height, and returns the axes.
Example. Toys gets a bar of height 500, Books one of height 320, and so on.
Notes. Keep the categories in the order given. Return ax.make_scatter(hours, scores) that draws one dot per (hours, scores) pair and returns the axes.
Example. The student with 1 hour and score 52 becomes the dot at (1, 52).
Notes. Use a scatter, not a line — dots live in ax.collections, not ax.lines.
