You can export a graphic widget as a .json file from one account and import it into the Widget Studio of another account.
First, on the Widgets Dashboard, open the 3-dot menu and click on Export to .json.

Then, open the Widget Studio to create a new widget and choose Import a widget form .json file.

Importing a widget will copy all the configuration except recommendation blocks, visit counter, custom data, events and actions linked to goals/events created in the original account.
