Scalable Vector Graphics (SVGs) are files that describe how to draw the basic elements needed to create an image: elements like lines, circles, polygons and more complex shapes. Unlike the images typically returned by most search engines (for example, JPG, GIF and PNG), SVGs can be stretched to any size without the quality of the image suffering. This makes them ideally suited for things like clip art, maps, logos, flags and scientific diagrams.
To search SVG exclusively in google,just click “Images” in the left-hand panel, then "Advanced Search” and then select the SVG filetype. If you want to impress your friends, you can also add “filetype:svg” to any normal search, such as [graph theory filetype:svg]:
Example searches: [world map filetype:svg], [flag filetype:svg]
