I have used ngx-graph to implement visualization of a DAG. It works perfectly during development and throws no errors. While in a deployed build, it stacks up errors in the console.
I guess it is looking for some provider but none is described in the package or demo. Here's my app.module.ts file :
import { NgxChartsModule } from '@swimlane/ngx-charts';
import { NgxGraphModule } from '@swimlane/ngx-graph'
import { BrowserAnimationsModule } from '@angular/platform-browser/animations'
...
imports: [
...,
NgxChartsModule,
NgxGraphModule,
BrowserAnimationsModule
]
