The easiest way to create an SVG illustration is to use graphic editors such as Adobe Illustrator or Sketch. Pick the one you prefer and create an icon (or download our source file). Most of what you create in these apps is SVG friendly, meaning that the graphics you create can be translated into code. The easiest way to realize that is to save an icon as .svg file, then open it with a code editor.
