Summary  
This chapter covers UI layout design principles—visual hierarchy, alignment, whitespace, and the five-second rule—to make dashboards faster to read, easier to trust, and more engaging.  

General domain of usage  
Data visualization dashboards (business intelligence reporting)

A working dashboard and a well-designed dashboard are not the same thing. In this chapter you'll learn the four design principles that separate reports viewers trust from reports they ignore: visual hierarchy, alignment, whitespace, and the five-second rule. You'll also take a structured look at the Summit Gear dashboard to identify exactly what the polish pass in the next chapter will fix.

This chapter sets the mindset before the hands-on work. By the end you'll have a clear picture of why design decisions matter and a specific plan for what needs to change on each page of the dashboard.

A viewer opens your dashboard and within five seconds says "I'm not sure what this report is about". Which design principle did you most likely violate?
