demo for using panToNode$ functionality

[pinkicious]

Is your feature request related to a problem? Please describe.
I cannot get the panToNode$ functionality to work for ngx-graph 6.1.0.
While I cannot find a lot of documentation about this functionality, it is hard to validate what i'm doing wrong.

Describe the solution you'd like
Is there a Stackblitz or example code available that demonstrates the panToNode$ functionality?

Thanks in advance!

Yeah, I would appreciate more information/example too!:)

How far have you come so far?
I oriented myself on the zoomToFit$ function since there are examples for it :^)

What I did so far:
TS:

import { Subject } from 'rxjs';

...

panToNode$: Subject<String> = new Subject();

 ...

select(node: any) {
    this.panToNode$.next(node.id);
}

HTML:

<ngx-graph ... [panToNode$]="panToNode$" </ngx-graph>

However, it does work when I click on a node, but it's not centering the node...
It just moves the whole graph to the bottom/right. There is an issue open for it tho.

On the latest version, there is a problem with pan to node
It suppose to be fix after #288

I agree that we need to have a demo for this.
