Navs and tabs But to send binary data by hand, there's extra work to do. Creating dynamic SVG elements with JavaScript There are many sources for binary data, including FileReader, Canvas, and WebRTC.Unfortunately, some legacy browsers can't access binary data or require complicated workarounds. You may want to use a custom viewport if you have more layers in your SVG but you want to pan-zoom only one of them.. By default if: There is just one top-level graphical element of type SVGGElement (
