This is my first time using SVG and I want to know if it is possible to create an animated line graph with an arrow. I have found multiple examples of animated line graphs without arrows, non-animated line graphs with arrows, and animated straight lines with arrows, but not exactly what I am looking for. I have attached some codepen examples I've been playing around with below. Does anyone know if this is possible/have a solution? It would be greatly appreciated!

Animated straight line with arrow (needs to stop at multiple points on path): http://codepen.io/alexandraleigh/pen/yVPYrY
I tried adding the path descriptions from #1 to #2 and it has the desired final graph, just no animations: http://codepen.io/alexandraleigh/pen/pNdgWR
I also tried adding the arrow marker from #2 to #1, but the arrow doesn't animate: http://codepen.io/alexandraleigh/pen/aBVdVY
I'm also open to using a plugin such as http://snapsvg.io/, but haven't seen any working examples that help my situation.
you can do this with offset-motion(old syntax: motion-path). Be aware that this is a heighly experimental feature. it currently only works in Chrome. More to the point i use the "old" syntax here as that is what currently works in chrome, but it will soon switch to the new systax...

</div>you can also do this with animateMotion, but svg animations are soon to be depricted. You will have to rewrite your code in any way sooner or later :-(
