Add renderPointRing without hover/focus and setPointRingColors for per-point ring customization

[NeverSeec]

It would be useful to extend point rendering capabilities with two new features:

1. renderPointRing without hover/focus

   • Currently, renderPointRing only shows on hover/focus. Adding an option to render rings persistently (without interaction) would improve static visualization of nodes.

2. setPointRingColors for per-point ring colors

   • A method to assign unique ring colors to individual points would enable better node indication (e.g., for states, categories, or thresholds).

Alternatives Considered:

• Overloading renderPointRing with a visibility option ('always' | 'hover-only').

Let me know if this aligns with the library’s direction! I’m happy to discuss or contribute.

That would be a nice feature to have, and we're open to contributions!

The focusedPointRingColor property essentially does what you want (persistently displays the ring), but it supports only a single point. Maybe we can extend this functionality to support multiple points.

Awesome! I’ll dig into this and see if I can make it work. Thanks!
