For example, if there are multiple tabs on a page, the pure DHTML approach would load the contents of all tabs and then dynamically display only the one that is active, while AJAX could load each tab only when it is really needed.
Note: $ and jQuery are the same object; choosing between them is purely a matter of opinion. Many scripts use this function simply to add some script interface, such as a link in a portlet. Then the main part of the code is executed after the user clicks on that link.
The central principle of D3.js design is to enable the programmer to first use a CSS-style selector to select a given set of Document Object Model (DOM) nodes, then use operators to manipulate them in a similar manner to jQuery. [8] For example, one may select all HTML paragraph elements (represented by <p>...</p>), and then change their text ...
