textAnchor

[sirrice]

When we apply an svg attribute in the vis mappings like textAnchor and set it to a constant value,

See the new paralle coordinates example in nest_func branch for example.

let vattlabels = canvas.text(attrstable, {
   x: vatt.get("attr", ["x", "width"], (d)=>d.x+d.width/2),
   y: vatt.get("attr", "y", ({y})=>y+15),  
   textAnchor:"middle", text: "attr", fontSize: "20pt"})

When this is rendered, the text-anchor attribute is added to the container and not the individual text nodes.
