You can include a diagram as part of an instructional note.
In theory, you might be able to create a grid-like view with the 'horizontal' appearance, but the number of columns is auto-generated (you can't guarantee 3). We haven't implemented it yet, but there is a display option to transform a series of select_one questions into a grid; while that would have something like the appearance, the data would be stored across multiple questions. Another option that we are planning to support in the future would be to have a sketch area that has the option for a default image (like a diagram of the intersection of street corner); that would allow an inspector to draw the location, but that wouldn't be stored as a data column in the database
Another suggestion, probably outside of the scope of this conversation, would be to use AppStudio to create a custom question appearance for the select_one question and then build a version Survey123 that uses it.
