Navigraph have updated their new developer blog found here with some new information on their upcoming update to their charts service.
The new update will include fully dynamic and interactive en-route charts!
If you are used to using the SkyVector service for route planning, these will look very familiar.
Not only are they great for getting a visual representation of the intended route, but also great if you want to manually create your own route.
Showing all FIR boundaries, individual airways, VORs and a lot more.
The new Navigraph Charts product which will be available early 2017
The entire blog post can be found on the Navigraph developer blog. I strongly recommend reading it.
