In the previous video I said that one of the main reasons why we want to use multiple views is because we want to be able to show different properties of the data simultaneously. Now, I want to dig a little deeper into that. The main question here is, how do we show different properties in different views? What does it mean to show different properties? I think there are two main classes of methods that enables you to show different properties of the data. The first one is about visualizing in the first view and in the second view different information. The second one is about visualizing information in a different way with a different visual representation. Of course both things can happen, and do happen at the same time. It is possible to show in the other view different information, and use a different representation. All combinations are possible. You can also use the same information in same representation, or different representation in same information and so on. So, more precisely, when we talk about Different Information, there are at least three different classes of situations where we are visualizing Different Information from the same dataset in the two views. The first one is when the second view is visualizing a subset of the items that are visualized in the first view. The second one is when the second view is visualizing different attributes of the datasets with respect to the first view. The third case is when the second view is visualizing the same data but at a different level of granularity. So, these are three different situations in which the two views are showing different information, but in a different way. So, it's either a subset, or a different set of attributes or different granularity. Again, this is also true here. These three ways of creating different information can also be combined together. Finally, when we talk about using different representation, again, it can be a lot of different solutions here. One example that is very common in interactive visual interfaces is to use a graphical representation in one view, and a tabular or textual visualization in the other view, and both views are representing exactly the same data, but it's represented with a radically different visual strategy. In the next video, I will start showing you specific examples of these combinations.
