I think you shouldn’t have put green circles for seasons in which these clubs didn’t play in the top two divisions (maybe a grey circle or no circle at all would have been better).
Some clubs have green circles for seasons in which they went bankrupt (for example Mantova and Como in 2017, or Modena who didn’t even completed the season in 2017/18) and a lot of them have green circles in seasons in which they were deducted points.
With all those green circles the situation seems a lot better than it actually is.
