FWIW I prefer my other current example (I'll wrap up a third one soon), procedural map generation and reflection bump map with SVG http://bl.ocks.org/monfera/21be9bb116a8e5b2423b706155fdb718 (click the map or move the mouse) or Nadieh Bremer's examples eg. http://bl.ocks.org/nbremer/0e98c72b043590769facc5e829ebf43f
Also if you want to generate SVG programmatically check out http://d3js.org and https://www.dashingd3js.com/svg-paths-and-d3js
