Can we preload canvas with an existing svg file?

I have a requirement where I have a town plot map and I want to draw a polygon against each plot to show the border of each plot

You can add the image to backgroundImage property as a background then allow users to draw on top of it. But this library doesn't support polygons. I would suggest you use another feature-rich library like tldraw
