List of default GoJS values and settings?

I’d like to customize the grid lines and would like to know their initial (default) values (line colors, cell size). Can you tell me where to find them please?

Thank you,
Eric

I guess we should improve http://gojs.net/latest/intro/grids.html to show the definition of the standard grid pattern that is Diagram.grid.

  diagram.grid =
    $(go.Panel, "Grid",
      {
        name: "GRID",
        visible: false,
        gridCellSize: new go.Size(10, 10),
        gridOrigin: new go.Point(0, 0)
      },
      $(go.Shape, "LineH", { stroke: "lightgray", strokeWidth: 0.5, interval: 1 }),
      $(go.Shape, "LineH", { stroke: "gray", strokeWidth: 0.5, interval: 5 }),
      $(go.Shape, "LineH", { stroke: "gray", strokeWidth: 1.0, interval: 10 }),
      $(go.Shape, "LineV", { stroke: "lightgray", strokeWidth: 0.5, interval: 1 }),
      $(go.Shape, "LineV", { stroke: "gray", strokeWidth: 0.5, interval: 5 }),
      $(go.Shape, "LineV", { stroke: "gray", strokeWidth: 1.0, interval: 10 })
    );

which displays as:

Thank you Walter.

I think it would be generally helpful if all the “built in” values in GoJS were documented somewhere (or discoverable).
