comment Why to do parentheses change the results of a calculation?
@alancalvitti It is left-associative, which is what the OP did here.

You probably want Abs@Sign@tmp3, which is the same as Unitize.

comment Is there a way to hide or toggle the visibility of code?
@chris Is there a way to hide it otherwise? I don't think you can fold a single cell.

comment 3D view of a route shown on a map
@yulinlinyu Maybe the default view in yours is different. Try flipping the map upside down...

comment 3D view of a route shown on a map
This shouldn't be very hard to do. Using Line or Arrow to draw the primitives, update the list of points to add a new point as time progresses. This gives you the list of frames for the movie. You can then use ListAnimate or Export as a gif or a movie. If you want a close up view from the top and move along the map as the direction changes, use ImageTake to focus on only a WxH rectangle centered at the latest point. I suggest that you make an attempt first and show us what you've tried.

comment Reduce distances between vertices of graph to minimum possible?
Yeah, CA is on the left. Oh well, was worth a try :) In any case, I do think that an approach like Daniel's answer is the way to go. You can then use the centers and radii from the optimization program and feed it to Graph

comment Reduce distances between vertices of graph to minimum possible?
Heh, that was what I tried too at first. Try this on your US graph: $ComponentLayouts = {"CircularEmbedding", "HighDimensionalEmbedding", "LayeredDrawing", "LinearEmbedding", "RadialEmbedding", "RandomEmbedding", "SpiralEmbedding", "SpringElectricalEmbedding", "SpringEmbedding"}; $PackingLayouts = {"ClosestPacking", "ClosestPackingCenter", "Layered", "LayeredLeft", "LayeredTop", "NestedGrid"}; Outer[Graph[edges, VertexShapeFunction -> vsf, GraphLayout -> {"ComponentLayout", #, "PackingLayout" -> #2}]~ Labeled~{#, #2} &, $ComponentLayouts, $PackingLayouts] // Grid

Something like in this Q&A is what Daniel was referring to. If you modify his answer a little bit to handle circles instead of squares, you end up with this, which looks pretty decent.

comment How do I define functions in TraditionalForm?
No, the intent is not clear — see the example in my above comment (I was editing it when you posted yours).
