SVGRenderer class

SVGRenderer can be used to render geometric data using SVG. The produced vector graphics are particular useful in the following use cases:

  • Animated logos or icons
  • Interactive 2D/3D diagrams or graphs
  • Interactive maps
  • Complex or animated user interfaces

SVGRenderer has various advantages. It produces crystal-clear and sharp output which is independent of the actual viewport resolution.

SVG elements can be styled via CSS. And they have good accessibility since it's possible to add metadata like title or description (useful for search engines or screen readers).

There are, however, some important limitations:

  • No advanced shading
  • No texture support
  • No shadow support
