I love data visualization but, TBH, the field is a bit of a mess and can be overwhelming and unapproachable, especially for beginners. In an effort to bring a bit of order to the chaos, I've been working on a "map" that brings many dataviz-related terms, types of visuals, skills, software products and books together into a single graphic that attempts to show how they all relate to one another, and to make the field more approachable.
