It's a "vibe map design", basically means you can design a interactive map theme by prompt text/image. It's one of the features in Tasmap (https://tasmap.app), a personal map creation tool, like google my maps, but focus on design, customize, and privacy control. I split it into a stand-alone page so you can try it without register. Looking forward to seeing your creation :)
Tip: An imperative prompt can achieve the effect you want, but a poetic prompt can sometimes bring surprises.
