how to drag an item from svg tag to any div or html

why we can’t drag any item outside svg tag. I read about svg tags and no where i found why svg tag doesn’t allow to drag any item outside the tag.

Is there anyway through which we can implement drag and drop functionality in svg, similar as following :

Instead of list, can i drag an item from svg, If not then why ?
To be more precise, can we drag and drop bubbles outside the chart area (svg tag)
