 Open up the file `Explore.scala`
 
+`data` is defined. Let's take a sneak peek at it.
+
+```scala
+creativescala.Explore.data
+val res0: List[creativescala.data.HadCrut5.Record] =
+  List(
+    Record(1850,1,-0.67456436,-0.98177195,-0.3673568),
+    Record(1850,2,-0.333416,-0.700901,0.034069024),
+    Record(1850,3,-0.59132266,-0.9339191,-0.2487262),
+    ...
+```
+
+Explain the data.
+
+`Record` is year, month, anomaly, lower, upper.
+
+What is a `List`? Zero or more elements, with a defined order.
+
+How can we get an understanding of the data?
+
+```scala
+creativescala.Explore.data.size
+// 2082
+```
+
+```scala
+creativescala.Explore.data.head
+// creativescala.data.HadCrut5.Record = Record(1850,1,-0.67456436,-0.98177195,-0.3673568)
+```
+
+This won't scale. Better to visualize the data.
+What should we visualize? For each year as a line of month versus anomaly.
