Unreadable architecture diagram

[nutjob4life]

The architecture diagram that appears in the README.md as well as on the AWS storage blog article that introduces the web client uses tiny, blurry fonts. It's nearly unreadable. It should be reexported in a much larger resolution/size (and perhaps with a transparent background) so as to be usable, especially by people with vision difficulties (think Section 508).

Another possibility might be to use Mermaid to create the diagram.
