   "CSS Shapes"     vs      SVG Shapes

<svg viewBox="0 0 32 32">
    <path d="M23.6 2c-3.363 0-6.258 2.736-7.599 5.594-1.342-2.858-4.237-5.594-7.601-5.594-4.637 0-8.4 3.764-8.4 8.401 0 9.433 9.516 11.906 16.001 21.232 6.13-9.268 15.999-12.1 15.999-21.232 0-4.637-3.763-8.401-8.4-8.401z" fill="#444444"></path>

SVG Filters Are More Capable

You can pass the output of one filters an input to another filter..

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <defs>
    <filter id="goo">
      <feGaussianBlur in="SourceGraphic" stdDeviation="10" result="blur" />
      <feColorMatrix in="blur" mode="matrix" values="1 0 0 0 0  0 1 0 0 0  0 0 1 0 0  0 0 0 19 -9" result="goo" />
      <feComposite in="SourceGraphic" in2="goo" operator="atop"/>
    </filter>
  </defs>

Icon Systems

 

SVG Icons Advantages Over Icon Fonts

  • Infinitely scalable & look crisp on all resolutions
  • Styleable via CSS (multi-colors)
  • Easier size control
  • Interactive and animatable using CSS, SMIL and/or JavaScript
  • Semantic markup
  • Fully accessible (incl. text contained in an icon)
  • Many tools available to make creation, interaction, embedding and spriting easier
  • Different embedding and fallback techniques

We don't download fonts; icons are what svg is for.

Accessible Data Visualisation & Charts

 

HTML5 Canvas

  • Content is currently not accessible
  • You need to provide alternative content between the opening and closing <canvas> tags
  • HTML5 Canvas Task Force added two new features to the spec to create accessible fallback Canvas content
  • Requires extra work to make content accessible (in all browsers)
