In our project, we are displaying a variety of labeled images (PictureMarkerSymbols). When more than one of these images are close together the text labels become impossible to read because they overlap. Is there a way to declutter the text in a GraphicOverlay by either repositioning the text or grouping graphics together?
Yes, right now this is quite challenging with the current API. We plan to support label decluttering in a future release, hopefully Update 2 or 3. It is on the roadmap.
