Data Driven UI Project
In this project, you will create a simple interactive UI that updates dynamically as the underlying data changes. Imagine a list or a set of colored boxes on a web page. As you add, update, or remove data, the displayed elements should reflect those changes instantly. This approach is at the heart of data-driven user interfaces, where what you see on the screen is always in sync with your data.

The key to building dynamic UIs with D3 is its data binding system and the enter-update-exit pattern. When you bind data to elements, D3 tracks which data items are new (enter), which already have corresponding elements (update), and which are no longer needed (exit).
- The enter selection allows you to create new elements for new data;
- The update selection lets you modify existing elements;
- The exit selection removes elements that are no longer associated with data.
This pattern ensures your UI always accurately reflects your data, making it easy to build interactive and responsive interfaces.
