Sometimes, designers try to squeeze massive amounts of data into one dashboard, and bluntly speaking, it turns into a mess. When everything seems important, nothing is important. Thus, be respectful to your users and avoid overwhelming them with data they won't be able to process.

Let the project goals, user needs, and the nature of data guide you in choosing the most relevant widgets and graphs. Ask yourself: "What specific problem will this dashboard help users solve?" The answer will reveal which metrics, properties, values, visuals, and data are essential for completing a goal and which are useless and should be removed.
