In the paper Configurations of points and topology of real line arrangements, Math. Ann. 374 (2019), no. 1-2, 1–35, doi
: 10.1007/s00208-018-1673-0, B. Guerville and J. Viu give families of line arrangements which define Zariski pairs distinguished by a link invariant. This paper can be found also in arXiv:1702.00922. Moreover, a simple way to compute this linking invariant is given.
In a subsequent paper, Fundamental groups of real arrangements and torsion in the lower central series quotients, Exp. Math. 29 (2020), no. 1, 28–35,

: 10.1080/10586458.2018.1428131, these authors together with E. Artal compute the fundamental groups for one of these pairs and prove they are not isomorphic. This paper can also be found in arXiv:1704.04152.
We provide two notebooks for the involved computations, which can be either downloaded or executed online in .
The first notebook studies carefully the arrangements while the second one can be used for other arrangements.
