Reaction: Jigsaw: Supporting Investigative Analysis through Interactive Visualization.

The paper provides a good introduction to the investigative tool called Jigsaw. The tool helps the user to understand connections between entities: persons, places, dates and organizations using 4 different views: List View, Graph View, Scatterplot View, and Text View.

In my opinion, each of those views complement each other, and they will be helpful in their own way. However, it will be interesting to see a geographic view that presents a map with different colors depending on how many mentions a country or region had.

Also, I don't think that the tool will be useful when you have large amounts of entities because you would have many labels, nodes, ineligible axis, or the need to scroll a lot, so it would be interesting to see how the tool would adapt to large amounts of text/entities.
