30. Inline or background image?
31. SVG in Sketch
32. SVG Export
33. PDF Export
34. Illustrator SVG Export
35. 100% width
36. Filling the space
37. SVG Map result
38. Optimisation
39. Separate DOM SVG nodes vs. Defs
40. Don’t use 3D transforms
41. Don’t Base64 encode for Android
42. Grouped elements result in a 7% faster paint
43. SVG is painted up to 11% faster with Use elements
44. Optimised (a little)
45. The bad
46. 3.0
47. Use canvas if you’re rendering all of the nodes, ever.
49. The great
50. Resolution independence past @2x
51. Mutable
52. Animate
