Description
Since the pointer transform only focuses one point at a time, if points are coincident (or nearly so), some points may not be focusable. Should the pointer transform allow focusing multiple points simultaneously, and then the tip mark could handle cycling between points, or showing multiple tips with collision detection? Or should the pointer transform support an interactive method of cycling through nearby points, say by clicking?

Research direction
No files or tests are named. Start by tracing the pointer transform and tip mark behavior for coincident points; the issue first needs a decision on multi-point tips versus interactive cycling before a completion condition can be defined.
