I would like to replace each of the red square nodes by a shopping cart tikzpicture (no text is needed inside the cart):

with the cart scaled to similar size of the square red nodes.

How can I replace the square nodes by carts? (e.g. c1, c2 and c3 will be three carts at the right of node 1).

There are 2.5 methods to make a TikZ picture a node:

1. Use path picture.


2. Use a savebox.


3. Use pics. This is strictly speaking not a node, hence "2.5" instead of 3 possibilities.

Let's focus on option 2. Your cart gets stored in a savebox. It can be the content of the nodes, or you can make it a style using node contents. (In this case you need to be a bit more carful with the syntax, node (C1) [cart]; works but node[cart] (C1); doesn't.) Then there are several off-topic comments:

• You were loading packages and libraries that you didn't use. I got rid of them.


• You were loading positioning but not using it. Instead of right of=A use the positioning syntax right=of A or right=<distance> of A. This makes it much easier to arrange the nodes.


• If you repeatedly use the same styles it is more convenient to use scopes.

All this is to some extent done in the following MWE (which is not fully optimized, though):
