Add more shapes and type of lines for shapes in display component

**Describe the problem you have/What new integration you would like**

Hi!

1. Could be very cool to have more shapes (triangles, etc...) in the display component.
2. Also, would very much like to customize the type of lines for the existing shapes (dotted line, etc...)

Regards,

Start by locating the display component and its existing shape and line rendering behavior. The issue names no files or tests, so first determine which shapes and line styles are supported and how the component is exercised. Done means the requested additional shapes and customizable line types are implemented with clear validation.
