Im using svgjs to create my shapes. How can I find the center point of an svg shape and add an element there? In my case a red dot. I can't find any information in the documentation for a method or something that helps in this situation.

You can use the method getBBox or alternatively getBoundingClientRect. Both methods give you an object with the properties x, y, width, height, which you can use to calculate your center.

Since you tagged your question with svg.js I will also give you a solution with svg.js.

// Vanilla
node = document.getElementById('myEl').getBBox()

// with svg.js
SVG.adopt(document.getElementById('myEl')).bbox()

The second solution gives you back an object which has cx and cy already calculated for you.

This method can be found in the docs
