Can teammates view the diagram without the app?

Viewers on the same site see the rendered diagram on the issue. Editing requires the macro, which any user on the site can open once the app is installed.

Does it support Gantt charts for sprints?

Yes. Gantt is one of the 26 supported types, so you can lay out sprint timelines directly on an issue or epic.
