Using:

1. Angular 9
2. NgRx
3. Angular Material
4. D3

npm i
ng serve

I hope that the projects that you work on, are as fun as this!

If time was not an issue, these are the things I planned on doing:

1. tests
2. Install Apollo
3. Adding GraphQL mock server and services
4. Using ngrx/Effects with required success and failure actions, I created a working stub in the branch effects
5. Adding Search box using pipe-filter on the list of "friends"
6. Making the graph window resize dynamically by listening on the window:resize event
7. Snackbar for notifications
