Fun fact: Erwise[0] was the first _graphical_ browser developed by a group of students in Helsinki University of Technology with Sir Berners Lee. Sadly there was no funding in Finland available at the time and they had to abandon the project and most of the group ended up working at Tekla, contributing to a bunch of cool AEC CAD technology (Tekla is now a Trimble subsidiary).
Not really. In Graz we had our better Hyper-G graphical browser before CERN, with a completely integrated system to ensure link consistency. Every browser was also the editor. In 1989. https://arxiv.org/pdf/2105.08057
At CERN they wanted to enrich gopher with multimedia data to share building plans and images of their complicated plans, in Graz we wanted to provide a rich teaching and information platform for students. Sadly we went commercial and not open source, so worse got better. Well, a session-less server as httpd was actually better.

No, as indicated in the submission the original WorldWideWeb.app (developed on a NeXTCube) is a graphical Web browser.
