In communicating and teaching humanities visualization become more and more important. One popular visual communication instrument are slides. More and more of them are shared on Slideshare. A very nice example is Sampling in Qualitative and Quantitative Research from Sam Ladner. The Senior Researcher at Microsoft Office shows us sampling methods and let us have a practical how-to-do. Her key themes are quantitative and qualitative assumptions in sampling, types of samplings, ethnographic and interview sampling and content analysis sampling.
Slide presentations can be awful boring. But, this one is simple and effective in the best sense, a good example in order to show that visualization in the humanities must not be directed against the text but can very well go with it.
By the way:
(1) In some of her 28 slides Sam Ladner also shows what qualitative researchers and what quantitative researchers do worry about. And she does this in a quite sympathetic manner!

(3) A very interesting project in order to visualize archival sources is Trading Consequences: A Case Study of Combining Text Mining & Visualisation to Facilitate Document Exploration from the Universities of Edinburgh, Saskatchewan and St. Andrews. It has been presented at the DH Conference 2014 in Lausanne, Switzerland
