We are looking for the associations 🕵️‍♂️

We are trying to create a visualization for our new pitch deck, and we need to show how 2 different things can combine and create 1 new and productive. So we imagine that it can be 2 different cities that are connected with bridges, it can be 2 parts of one detail, it can be 2 pieces of the puzzle. But maybe you have more associations? We need to show that these 2 are not good separately, that need to unite to create something unique.
