d3.js The Element


Example

SVG doesn’t currently support automatic line breaks or word wrapping, that’s when comes to rescue. element positions new lines of text in relation to the previous line of text. And by using dx or dy within each of these spans, we can position the word in relation to the word before it.

Case: Annotation on Axes

For example, when we want to add an annotation on y Axe:

svg.append("g")
  .attr("class", "y axis")
  .call(yAxis)
.append("text")
  .attr("transform", "rotate(-90)")
  .attr("y", 6)
  .attr("dy", ".71em")
  .style("text-anchor", "end")
  .text("Temperature (ºF)");
