Thanks, this is useful. GraphLayout -> "LayeredEmbedding" does help. But for my more complicated use case, it messed up the layers, while obsolete/deprecated LayeredGraphPlot was more helpful with a proper tree structure with edges always pointing downwards (e.g.), never upwards. Is there an ever better way? (My graph is not a proper tree, but close.)

Sorry, no time to dig into this ... that's why this is only a comment. In short, I think the only reason GraphPlot functions are still around is backwards compatibility...

This is likely because *GraphPlot functions are the old way to visualize a graph, from before when Mathematica got a Graph datatype. I'd consider them deprecated. Originally they just took a pair-list or a rule-list, not a Graph. They've been updated to support Graph, but it seems the conversion loses both labels and names, and keeps only vertex indices. You can either convert on your own (Rule@@@EdgeList[g] will be accepted by GraphPlot), or you can use the new way to visualize the graph, SetProperty[g, GraphLayout -> "LayeredEmbedding"].

mentioning edge labels and more general GraphPlot
