Chapter 7. Exploring Data with Reports
In the next step, our third agile sprint, we’ll extend our chart pages into full-blown reports (Figure 7-1). In this step, charts become interactive, static pages become dynamic, and our data becomes explorable through networks of linked, related entities with charts. These are the characteristics of the reports stage of the data-value pyramid.

Building Reports with Multiple Charts
To build a report, we need to compose multiple views on the same entity. The charts we made in the previous chapter will serve us well as we increase interactivity to create reports. Let’s create an email address entity page and add a tag cloud for related emails to give us something closer to a report.
We’ll start by creating a relation that shows the most related email addresses. Check out ch07/pig/related_email_addresses.pig.
