Discussions in The Hobbit by Hanna Kumpula

I wanted to explore the discussions in The Hobbit by J.R.R. Tolkien. Only those words the characters say aloud are visualised. The visualisation shows the amount of discussion in each chapter as well as who of the characters are speaking and when. Characters come along as they are introduced but they don't leave the visualisation even though they are never heard or seen again in the novel.
Visualisation is inspired by sound waves and DNA test sheets. Data was collected by hand from a paperback novel, processed in Excel and visualised using Illustrator. I wanted to explore how this type of visualisation could be made by hand and not using computers.
