How to call a function on 'load' event in d3.js?

@arnoldo.moen 

In D3.js, you can use the on function to attach an event listener to an element. To call a function on the load event, you can follow these steps:

1. Select the element you want to listen for the load event on. For example, if you want to listen for the load event on the window object, you can use d3.select(window).
2. Use the on function to attach the event listener. The first argument of the on function is the event type, which in this case is 'load'. The second argument is the callback function you want to call when the event is triggered.

Here's an example that demonstrates how to call a function on the load event in D3.js:

d3.select(window)
  .on('load', function() {
    // code to call the function on load event
    myFunction();
  });

function myFunction() {
  console.log('Load event triggered');
}

In this example, the myFunction function is called when the load event is triggered on the window object. You can replace myFunction with your own function to be called on the load event.
