Context. Six weeks of site visitors. A line makes the direction of travel obvious — and a title makes the chart self-explanatory.
Your task. Write make_trend(df) that draws a seaborn line plot of visitors over week, gives the chart a title (any wording), and returns the axes.
Example. sns.lineplot(...) then ax.set_title("Weekly Visitors").
Notes. sns.lineplot returns the axes — keep a reference so you can title it.
