Thanks so much! There are currently no methods for generating charts. It's something I'd like to expand upon eventually - the space travel and starship stuff was definitely the hardest part of this.
A good way to approach it might be to generate astro-nav routes the same way you might do point crawls in other games. And then the travel lanes/routes might be a mix of direct (when possible), or avoiding hazards like asteroid fields, political zones, etc. I think in most cases any point could connect to just about any other point, but including gaps in the routes the PCs have access to can be a good challenge. And it gives them something to spend credits on if they are really into having the most convenient routes and updated star charts.
