Explain, what is the use of “enter” and “exit” selection in d3.js ?..

Answer / Megha Saxena

In d3.js, the `enter` selection represents the new data that needs to be appended to the DOM, while the `exit` selection contains the elements that are no longer needed (i.e., those whose corresponding data has been removed).
