My Question

Hi, I have two questions on which I would like some more information or suggestions:

1. I want to create a 2D view mode, in which the user is only able to see the data from a top-view (nadir/bird eye perspective) and is only allowed to zoom and pan. Is there a way I can achieve this? Couldn't find any examples or documentation that helped me in this matter.

2. I noticed some added functionalities (#3298), stating that labels can be displayed in bold and/or italic. I would like to implement this into my code, but I am lacking the knowledge how to do so. Would someone be able to produce an example with the right syntax?

Appreciate any help!
