I love charts and infographics. I believe they are usually extremely effective in compressing a large amount of information in a manner that attracts and informs. Long chunks of text are often intimidating and may sometimes scare potential readers away if they seem like a big time commitment.
Flowcharts like this one are inviting and fun to look at. Well, if the subject matter interests you at all like it does me. SF Signal created this great chart called "A Guide To Navigating NPR's Top 100 Science Fiction and Fantasy Books." It recommends books based on your previous reads and current preferences, and it's great.
As an alternative, they have developed an interactive version of the same information. Click here if you prefer pushing buttons.
