How does data binding work in D3.js?

Data binding in D3.js connects data to DOM elements, allowing you to create visualizations that update dynamically.

Can you give me a simple example of data binding?

Sure! You can use the data() method to bind an array of data to a selection of elements, like this: d3.select('ul').selectAll('li').data(dataArray).enter().append('li').text(d => d);

What happens if the data changes?

If the data changes, you can use the update pattern to rebind the new data and update the DOM elements accordingly.

Are there any common mistakes to avoid with data binding?

Yes, a common mistake is not properly handling the enter, update, and exit selections, which can lead to incorrect visualizations.
