To avoid directly accessing properties in d3.js, you can follow these best practices:

1. Use data binding: Instead of manually accessing properties of data elements, use data binding methods provided by d3.js to bind your data to DOM elements. This allows you to work with the data in a more structured and organized way.
2. Utilize scales and transforms: Use scales and transforms provided by d3.js to map data values to visual properties such as position, size, and color. This helps you avoid directly accessing data properties and ensures consistency in your visualizations.
3. Use d3's selection and manipulation methods: Instead of directly accessing properties of DOM elements, use d3's selection and manipulation methods to select and update elements based on data. This allows you to work with elements in a more flexible and efficient way.

By following these best practices, you can avoid direct property access in d3.js and create more maintainable and scalable visualizations.
