Any tools for generating side view (vertical) maps from minecraft worlds?

To clarify, I'm thinking specifically either a mod that can do this in game, or an external program that can take in a world folder and generate an elevation. By elevatioin or side view map I mean how (for example) in Xaero's Worldmap you can select an area and export a 2d top-down (plan) pixel art map. Is there anything that can instead export a selected area as a vertical side view in the same way?
