Add Vertex boundary color (or, how to encode multiple style fields in CSV)

[milo-trujillo]

Hello! I am trying to set the outer color and fill color of a vertex separately - for example, setting the outline to light grey and the fill color to light blue to de-emphasize some vertices in an illustration.

The color Vertex attribute controls the fill color, but not the outline color, which remains black. Instead, it looks like I need to set the tikz style, like:

\Vertex[style={color=black!20,fill=blue!20}]{A}

This works for an individual vertex, but I cannot figure out how to add the same rules to a CSV. I've tried a few variations on:

id, x, y, label, style
v0, 0.238, 3.926, v0, black!20,fill=blue!20

Presumably this doesn't work because we can't have a comma in the CSV value. Escaping the comma, either with backslashes, {black!20,fill=blue!20}, or "{black!20,fill=blue!20}", has not worked. Breaking the single style field into two style fields hasn't worked, either. I've tried using space-separated .dat files instead of CSV, but have been unable to get \Vertices to read them.

Is there a way to accomplish what I'm trying to do? Or, ideally, would it be possible to add some kind of outlineColor attribute to tikz-network vertices to make this process much simpler? Thanks!

I finally find the method in the comments of issue. Just add one sentence in the document:"
\SetVertexStyle[LineColor=black!20]", and compile in the .tex file, then get it. Attention the default engine is pdflatex and latexmk. If you use xelatex, it will go wrong.

This will set the vertex style for all vertices, correct? I am trying to set the style per-vertex as part of the CSV file, so that some vertices could have a LineColor of black!20 while others can have a LineColor of black, letting me highlight parts of the illustration.

tikz-network parses the style field again internally, so values like black!20,fill=blue!20 tend to break even if you quote them.

You can define a named TikZ style in your TeX file:

\tikzset{
  deemphvertex/.style={draw=black!20, fill=blue!20}
}

Then use just the style name in the CSV:

id,x,y,label,style
v0,0.238,3.926,v0,deemphvertex

That should give you a light gray outline and light blue fill.
