The Scalable Vector Graphics format was widely and eagerly adopted by web designers on account of both its ease of use and its alleviation of the bandwidth strain that the client and the server both face when trying to mutually transfer large files. Optimization, as a term, encompasses multiple goals that relate to providing an efficient user experience free of long periods of downtime. A website that uses SVG to express its aesthetic design can be said to have optimized its content for clients' browsers and Internet connections because it eschews heavy image files in favor of crisp lines of code that would be easily reconstructed by many more web users' browsers. This also optimizes the website in terms of search engine prominence because Google and other engines consider how easily a website's content loads to be representative of a website that readers would actively want to consume.
However, the SVG format also exists as a higher medium for digital art in its own right. While many websites are content to only use SVG as a stand-in for visual theming as much as necessary, the mechanically driven components of SVG code can be manipulated to enliven elements of web presentation that are often left alone otherwise. In one case in point, a website can have a customized SVG animation take the place of a stock animated icon that tells the reader that something is actively being loaded and not yet ready to display. Since the user will likely be accustomed to circular loading icons that rotate clockwise, a more creative website can show an icon resembling a hoop of coursing electricity, for example.
This example of an eletricity-themed loading icon is hosted on codepen.io, where it is revealed that the brunt of the syntax responsible for it is contained in a JavaScript file. While the electric effects may appear blocky when viewed close-up, the icon can easily be displayed in much smaller dimensions — at which point both the dynamically rendered electric lines and the smoothly rotating and blurry hoop-like shape behind them can look far more convincing.
