This talk on LightGraphs was presented at JuliaCon 2018 by James Fairbanks and Mathieu Besançon. It covers what LightGraphs is, its scope and its relation to other packages and how to use it as a package developer.
This second talk on the JuliaGraphs ecosystem is a retrospective of the year and what we've learned developing and maturing the packages towards the 1.0 version.
