I can draw 3 lines this way:
sns.lineplot(x="week", y="mean", data=df)
sns.lineplot(x="week", y="min", data=df)
sns.lineplot(x="week", y="max", data=df)
So we have here min max and average value, they have precomputed before:
I want want fulfill with color between min and max, it have to look this way:

How to do that?
