Graph of connections to external services, for the golang language.

The image_connections console utility is designed to display all connections to external services of any repository in the Golang language in the form of a diagram (graph) in .graphml format, which can be converted into a .jpg image, etc. The source code of the repository is automatically parsed to find imports of external service modules. It is necessary to understand what services this repository interacts with, to study or better understand the call structure of the source code. Displayed:

• the name of the current repository
• names of external services, arrows to them

Sample execution (pictures) can be found in the examples directory

Configured to display the following services:

• PostgreSQL
• MSSQL
