You can draw any line you want. From something crazy and nonsensical to something that looks nice and smooth like the ones here. The fact that the lines “look” nice means nothing if they are not a realistic representation of the distribution of the data.
So, the lines might be pretty but not significant but we can’t tell without a measure
