Can you insert a line break in text when using d3.js? [duplicate]

Since you already know where you want to break the text, you could consider just adding separate elements.

.append("text")
  .attr("dy", "0em")
  .text("line 1")   // "line 1" or whatever value you want to add here.

And then for the second line, just add an offset

.append("text")
  .attr("dy", "1em") // you can vary how far apart it shows up
  .text("line 2")   // "line 2" or whatever value you want to add here.
