Description
ideally, tiny, single-path SVGs where the path d attribute can be reused for both the svg elements of hover points as well as Path2D cached paths for canvas draw.
https://github.com/grafana/grafana/pull/30192
these can be in the core if they're small and visually distinctive:
- circle
- square
- triangle
- star
- plus
- asterisk
- rhombus
- cross (rotated plus?)
e.g. tiny star:
<svg viewBox="0 0 260 245"><path d="M55 237L129 9l74 228L9 96h240"/></svg>

Research direction
Start by locating the marker-rendering code for hover-point SVG elements and the cached Path2D paths used by canvas drawing. Compare the requested marker shapes and shared SVG path data with the linked pull request. Done means the listed visually distinctive markers use reusable, single-path SVG data in both rendering paths.
