It is fairly straightforward to draw hex maps using Campaign Cartographer, providing you have access to one of the hex-map styles. I did a series of small test-maps in such a style back in 2023 here, where you can see both the snap-grid placement of symbols and terrain hexes, coastal shading, and, by scrolling further down the page, some samples where I redrew the coastlines by-hand. Adding roads and river lines would be fairly easy as well, as they're simply coloured lines of whatever style and thickness you prefer, and which can be drawn freehand, or using the hexagonal snap-grid.

@mike robel here has created a number of historical wargame hex-maps. This is his most recent topic on the subject. He can doubtless advise further on the subject, given many of his maps are based on real-world examples.

Obviously, we need some entwined knotwork wyvern designs for the furniture, but it's otherwise looking wonderful so far 😁😉🐲!

Cthulhu City is a great period style, though the final map of the three above seems a little bright and almost sunny for a Vampire City, perhaps? 🧛😎

I'm sure we're all shocked to learn you don't remember every one, and all the time-codes for every single item discussed in them, Sue 😉!

Well, I'm at the stage now where I'll probably just get to be usefully familiar with about 25% of CC3+, and then they'll move us all to CC4 😎!
