SelectAll function is used to select all the div elements on the page. The return of this function call is a D3 selection object that contains all the three div elements. Immediately after that, on line B, the attr function was called on this selection to set the class attribute to red box for all three div elements. As shown in this example, the selection and manipulation code are very generic, and will not change even if now we have more than three div elements on the page. This seems to be an insignificant convenience for now, but in later chapters, we will show how this convenience can make your visualization code simpler and easier to maintain.
