Overall, the good dashboard design is successful when it reduces the effort required by the end user to be as minimal as possible when they attempt to interpret and use the data presented in front of them to make decisions. We recommend establishing a hierarchy - more important things at the top, less at the below, so the viewer’s eye naturally goes on a journey. If they can’t engage without feeling overwhelmed, they’ll probably move away from your dashboard - which definitely isn’t ideal after all the effort you put into it.
