A Cartoon Guide to Flux by Lin Clark.
From the webpage:
Flux is both one of the most popular and one of the least understood topics in current web development. This guide is an attempt to explain it in a way everyone can understand.
…
Lin uses cartoons to explain Flux (and in a separate posting Redux).
For more formal documentation, Flux and Redux.
BTW, in our semantically uncertain times, searching for Redux Facebook will not give you useful results for Redux as it is used in this post.
Successful use of cartoons as explanation is harder than more technical and precise explanations. In part because you have to abandon the shortcuts that technical jargon make available to the writer. Technical jargon that imposes a burden on the reader.
What technology would you want to explain using cartoons?
