i'm creating a competition table dynamically with jquery and want to stroke connection lines between the single competition layers. I'm creating them with jquery as mentioned with the svg namespace e.g. Function for creating SVG Element with Line Tag as Child

It all works properly up to adding the elements to the DOM seeing in the inspector DOM Tree Structure of SVG Element with Lines

But at the site directly the lines are not showing up. They havo to be in the red rectangle

I've ended up testing several hours with this but not finding the Solution.

Thanks for help :)
