To refer viewpoints from tables, I need to chenge the Output interface and that affects other unrelated files like dot.go.
If you have better idea to implement this feature, kindly let me know.
I appletiate it.

It may be better to add a Viewpoints field to the Table.

@macoto1995 You may have it implemented as is. I will correct it on my end!

Oh..Sorry I missed your new comment for a few days.

It may be better to add a Viewpoints field to the Table.

I have some concern about this solution.
Since Viewpoint has Tables as children, it would be infinite loop.
Plus, to render link to viewpoints from the markdown, the OutputTable function has to know the index of the viewpoints, which is not included in Viewpoint type.

So I suppose that it's better to have TableViewpoint type like below.

struct TableViewpoint {
    Index Int
    Name String
    Desc String
}

Kindly, let me know what you think.
I'd work on this way for now.
Thank you.

Yes. In fact, recursive relationships are everywhere (e.g. Table.ReferencedTables and Table.Column.ParentRelations ).

Plus, to render link to viewpoints from the markdown, the OutputTable function has to know the index of the viewpoints, which is not included in Viewpoint type.

fmfm, indeed. Good point.

So I suppose that it's better to have TableViewpoint type like below.

LGTM. So far I have no better ideas either.
