Most reveal.js based presentations you can press "esc" and get a slide overview, although that's of limited use. Slides in general are simply not as useful as a reasonable web page if they don't have the presentation along with them in audio or video. It's a peculiar part of HN culture to link to just slides, I don't know of any other group that does it.
A far better introduction to sci-kit learn is the project's examples page, http://scikit-learn.org/stable/auto_examples/index.html, which you can use to get example code and data to generate each type of graph. The documentation on the rest of the site is also of very high quality.
