role graph serialization for front-end usage

[GopherJ]

I have a covid-19 project which shows virus propagation chain, so I came up with a small idea of serializing role links which can be useful for analyzing.

basically the serialized json should be similar to the following to be used by frontend libraires such as d3.js

{
  name: "alice",
  children: [
    {
       name: "bob",
       children: [
         {
            name: "eve".
            children: []
         }
       ]
    }
  ]
}

Or a more general format:

{
  key: "A",
  value: 5,
  children: [
    {
       key: "B",
       value: 1,
       children: [
         {
            key: "C".
            value: 3,
            children: []
         }
       ]
    }
  ]
}

The second format is more general but actually we dont care about edges so I prefer the first example.

A difficulty of serialization is circular link.

Visual analysis is good idea. Yang had the same idea.

Actually I planned to have this feature in the new Casbin dashboard project: https://dashboard.casbin.org/ but actually no progress for now because we are just in lack of developers :(

Casbin dashboard is deprecated.

We will visualize the role inheritance in Casdoor web portal UI.
