Greetings of the day!!
As predicting only based on the nakshatras direction is not effective as there are many peoples born in this nakshatra as we need to analyse your birth chart and see according to the planets position in your birth chart which will be your lucky direction, lucky number of flat, lucky floor and lucky color etc.
As a basic concept and the answer to your query is the lord of vishakha nakshatra is guru so the direction of the Planet guru is Norht East Opening.
Thanks & Regards,
