How to render path visualization in c3 ?

Hello

I created a character that moves using the "pathfinding" behavior and now I need to render a visualization of the path that it will move, but if I use "line drawing" in the canvas plugin, the edges are not rounded.

I did this in c2 using this canvas plugin and Bezier curves, but I need to do the same in c3, and there are no Bezier lines there

Please tell me how I can make the visualization of the path with smooth edges in c3, as in the attached video

Aside from a feature request you would have to split the path up and make your own curves using the interpolation expressions.
