Question: Default Styles (or theme)? about dotnetgraph HOT 3 OPEN

Thanks for your message.
So, basically, you'd like to set a default node/edge stlye on graph object? And then it's applied to every child without specified style?

Yes, I don't have a well thought out design, but here are some things to consider:

• Breakout styles from DotNode, DotEdge, and DotSubGraph
  -- DotNodeStyle: Color, FontColor, FillColor, Shape, Style, Height
  -- DotEdgeStyle: Color, FontColor, ArrowHead, ArrowTail
  -- DotSubGraphStyle: Color, Style
• DotNode, DotEdge, and DotSubGraph could have a very minimal default style, but would have an optional constructor param to override the default scale
• DotGraph could implement the builder pattern to
  -- set default styles for nodes, edges, and subgraphs
  -- add nodes, edges, and subgraphs
  -- see psuedo code below

var myGraph = new DotGraph("myGraph", directed: true)
	.SetDefaultNodeStyle(new DotNodeStyle(Color.Red, Color.White, Color.Blue, DotNodeShape.Box, DotNodeStyle.Solid))
	.SetDefaultEdgeStyle(new DotEdgeStyle(Color.Orange, Color.White, DotEdgeArrowType.Normal, DotEdgeArrowType.Normal))
	.SetDefaultSubGraphStyle(new DotSubGraphStyle(Color.Gray, DotSubGraphStyleAttribute.Solid))
	// Add a node using default style above
	.AddNode("NodeA")
	// Add a node using a non-default style
	.AddNode("NodeB", new DotNodeStyle(...))
	// Add an edge using default style above
	.AddEdge("NodeA", "NodeB") // Should find above node elements by name; create new nodes if not found
	// add an edge using non-default style
	.AddEdge("NodeB", "NodeA", new DotEdgeStyle(...))
	//...same pattern for subgraphs

I hope this helps spur some ideas, but feel free to continue the discussion and put me to work once we have a design you're happy with.

I like the idea of making styles separate object/class.
I will start some POC and make a draft PR to see how it goes.
Sorry for my late answer.
