We have a site.
There is a SVG-image on that site.
To add an element to the SVG-image we need the createElementNS method.
First parameter of this method is nameSpace.
We need the SVG-namespace.
The second parameter is the shape name.
Let it be the circle shape.
Let’s appEnd the circle to the container.
That’s all.
The element has been added to the SVG-image.
To make the circle more visible let’s make it big and orange.
Here it is.
Big and orange.
