D3 - show/hide text of only clicked node

I am trying to show/hide text of a node in D3 on click. I tried using the following code:

var node = svg.selectAll(".node")
  .data(json.nodes)
  (...)

node.on("click", function() {
  if (textShowing) {
    node.select("text").style("visibility", "hidden");
  } else {
    node.select("text").style("visibility", "visible");
  }
    textShowing = !textShowing;
 });

The code results in text property of all nodes showing/disappearing on click of any of those.

How can I affect the text property of only the clicked node?
