How to draw map marker on svg image

Hi,
I am new to xamarin and developing a cross-platform app using xamarin forms PCL way.

I have a map image in svg format. I am using SkiaSharp library to load that image on my UWP application through PCL. I have 1 ListView having names of locations. I want to draw annotation or location marker on image, on click of the respective list view item.
For ex: If I will click on XYZ location the marker will be shown on the particular location.

This functionality can be easily achieved by using any map api or xamarin maps, But my problem is I can't use any map api and have to show location on image only.

Please Suggest any solution. Any help would be appreciated.

Thanks in advance.
