I am making an html page with an svg of Missouri counties. I need each county to be its own area on the image map so I can handle display different data when each is hovered over. I also need to do this for all 50 states eventually, so I was looking for something to do it automatically.
Here is the link for the svg https://upload.wikimedia.org/wikipedia/commons/e/ee/Blank_map_of_Missouri_with_counties.svg

I have found sites like https://www.image-map.net/ but outlining each county individually is very time consuming. I am looking for something similar to the magic wand tool so I could just click on each county, or pretty much anything so I don’t have to make each point myself.
