 ## Selections Using a Custom SVG
 
 
-In the above example, we added a rectangular selection. You can also render a custom SVG for a selection by defining a `path` that can include single or multiple polygons. Here, we create a selection with a single polygon path "M2,6.5L4,7.5L4,6Z".

 Please note that multiple polygons e.g. "M0,0L0,10L10,10,L10,0Z M2,2L2,8L8,8,L8,2Z" could be used to subtract certain regions from the selection.
