Is it possible to download data (API) from Vkontakte?

Question

Database

Is it possible to download data from Vkontakte about users, communities, posts, etc., etc., how can this be done in FaceBook?
Only recently I started building network graphs and it would be very interesting to have such data, for example, to build a graph of my friends or a graph of communities in which I am a member.
And not only their own, but for example a count of people who are in a particular community?
Thanks in advance!
