(A) Lines are the stories of entities of one type, in this case of the type people, that evolve along the horizontal axis, that here represents entities of a second type which is time (aggregated by months). Small vertical bars are constructed relationships, positioned in the intersection of both axes of the entities that compose them. In our case, these relationships represent entities that appeared in news articles. For example the relationship highlighted in red indicates all people that appeared in news articles in August 2012. Relationships can have zero or more internal nested entities (a third type of entity). These nested entities can be seen as a mini-story by interactively expanding the relationships (B). For example, here we see details in August 2012, including the nested location entities that tie people to places in the articles, and more precise date information. The type of entities on the horizontal axis, the vertical axis and the nested entities can be changed with selectors in our tool. For example, in (C) we can see the stories of people related by locations instead of time (time is the nested entity). The red circles across images indicate where the entities that contribute to the highlighted relationship in (A) appear in the other views.
