In D3.js, you can remove a selected item from a list by using the remove() function. The remove() function is used to remove the selected elements from the DOM. Here's an example of how you can remove a selected item from a list:

1
2
3
4
5
6
7
8
// Select the list
var listItems = d3.select('ul').selectAll('li');

// Select the item you want to remove
var selectedItem = listItems.filter(function(d) { return d === 'Item to be removed' });

// Remove the selected item
selectedItem.remove();


In this example, we first select the list of li elements within a ul. We then use the filter() function to select the item we want to remove, based on a specific criteria (in this case, if the data of the item matches 'Item to be removed'). Finally, we call the remove() function on the selected item to remove it from the DOM.


Keep in mind that this is just a basic example and you may need to adjust the code based on your specific requirements.
