Here's an example:

(setq my-svg-data
      "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?><svg xmlns:svg=\"http://www.w3.org/2000/svg\" xmlns=\"http://www.w3.org/2000/svg\" version=\"1.0\" width=\"223.51666\" height=\"223.76907\" id=\"svg2\"><defs id=\"defs4\" /><g transform=\"translate(-191.24778,-211.49836)\" id=\"layer1\"><path d=\"M 408.57145,369.50505 L 333.90781,368.26904 L 290.56166,429.07444 L 268.66485,357.68315 L 197.44078,335.24841 L 258.57144,292.36219 L 257.8987,217.69136 L 317.57633,262.5775 L 388.38462,238.86313 L 364.13677,309.49051 L 408.57145,369.50505 z\" id=\"path2399\" style=\"opacity:1;fill:#ff0a0a;fill-opacity:0.264574;stroke:#000000;stroke-width:12.38599968;stroke-linecap:round;stroke-miterlimit:4;stroke-dasharray:none;stroke-dashoffset:0;stroke-opacity:1\" /></g></svg>")

(setq my-svg-descriptor (create-image my-svg-data 'svg t))
(insert-image my-svg-descriptor)
