Greetings, Cartographer's Guild. I'm brand new to this forum, though maps have been a hobby of mine my whole life. Whilst scouring the internet, I found very little in the way of resources for varied projections, and while I know many people do not feel the need to go so far as choosing projections, I firmly believe in having the option to. As such, over the past few days, I've manually done the calculations necessary to put together a coordinate grid of the lovely Winkel Tripel projection--a personal favorite--that features a 15 degree graticule, and which is in .svg format so that it can be scaled to suit whatever needs you may have. Further details are in the description on the DeviantArt gallery post, here.
