Is it correct to use "each of which" to connect two sentences?

The meaning of each of which is each of them

The figure is composed by several panels, each of which showing a country.

I am not sure if it makes sense

Answer

Everything is fine except:

1. You should change "showing" to "shows." Use the Simple Present to describe enduring qualities, and conjugate it as "shows" to match the singular "each."

2. We normally collocate "compose" with "of" rather than "by."

3. Add "different" before "country" to clarify that the panels don't all show the same country.

The figure is composed of several panels, each of which shows a different country.
