[pratyushbanerjee]

Description

Add item interaction mode for Line that triggers tooltip when hovering over a particular area near points on the line

Related Issue

Motivation and Context

Voronoi method for tooltips on Line does not allow interaction with elements behind the line. item interaction mode allows for more precise interactions with the points on the Line and allows interaction with elements behind it.
