Takeaways:

  • D3 selections allow you to modify DOM element HTML Text with the .text operator
  • D3 text operator works as a getter and setter
  • For it to work as a setter, you pass in the text you want to define
  • You can set the text value as a constant you pass in or you can have a function (named or anonymous) evaluated for each element in the selection
  • For it to work as a getter, you do not pass anything into the text operator
  • If the text exists, then you get the value
  • If the style does not exist, then you get a ""
  • Using the D3 .text as a setter, if you pass in a "null" as the value, then it deletes the text from all of the elements in the selection
