Some people recite Qur'an near graves of their relatives. Is this wrong?

The question is why do they read Qur'an at the graveyard? They do not have to go to the graveyard to read the Qur'an. They can read the Qur’an elsewhere and can make dua'- invocation to Allah from anywhere for the deceased. Allah says that He hears all invocations. We do not have to go beyond the limits set by the Sunnah.

Allah knows best.
