In this chapter we have seen how data can be visualized to understand and read a report just by looking at it. When you select and implement the appropriate visualization technique then users will not have to spend a lot of time interpreting numerical information but they will be able to see what's going on and get a clearer picture of the KPI in the report. As they say, a picture is worth a thousand words, this is of course also very true in reporting. We have seen how to use images, data bars, and indicators to create KPIs, Sparklines and charts to indicate and spot trends, and used the map to display geographical information.

In the next chapter, I will explore another type of report, the document report.
