An initial version of this code is described here. Since then, I've done a bit to integrate temporal graphs using this code (e.g. graphics under entities). The design goal is to embed relevant information, much like a sparkline. This information can disambiguate entities (e.g. the John Smith with a criminal record versis the legions without) and provide temporal context for the sentence. For example, does this sentence refer to something that occurred again?

Since I was responsible for various text displays at Palantir, I thought exploring this avenue was useful. I think integrating contextual information makes reading a document easier (entity disambiguation is visual), less error prone, and more connected. However, it never materialized into the live product.

Better support for graphic generation would be a great extension to this project. The curious should check out Example1.java for some pointers on how to put sparklines under regions of text.
