Takeaways:

  • d3.selection.on(type[, listener[, capture]]) adds an event listener to each element in the current selection
  • D3 invokes the listener in the same way it invokes other D3 operator functions - by passing the current datum "d", index "i", and the "this" context as the current DOM element
  • When a new D3 transition starts, it cancels any prior transitions, even those that were scheduled but have not yet been run
  • D3 allows you to construct multi-stage transitions through the use of the chain syntax
  • As long as D3 transitions are chained to another D3 transition on the same JavaScript command, D3 does the hard work of tie-ing the transitions together so they will be seen as one multiple-stage transitionexecuting one right after another
