This is a UI for the map generation library created by mewo2. You can find the library at github and the creator's write up. I have no affiliation with mewo2. This is just a tool to make generating maps easier
You can adjust the parameters here then hit generate map to create the image. You can then edit the names of the locations. Finally you can download the generated svg image by hitting the download svg button. Once you have downloaded it you can make further edits in an svg editor such as inkscape.
