Part of Course: D3 V4 Tutorial
 

Takeaways:

  • D3 Data Join results in three virtual selections - UPDATE, ENTER, EXIT
  • The ENTER selection gets data objects that were not bound to DOM elements
  • The UPDATE selection gets DOM elements that had data objects bound to them
  • The EXIT selection gets DOM elements that did not get any data bound to them
  • Depending on which D3 Data Join Scenario you are in, the Enter, Update, Exit selection will be empty or non-empty
  • The UPDATE selection can be accessed from "selection.data(dataset)"
  • The ENTER selection can be accessed from "selection.data(dataset).enter()"
  • The EXIT selection can be accessed from "selection.data(dataset).exit()"
