Into word2vec

we’re trying to go deeper into word2vec algorithms. few question seems to appear :

How to visualize/represent vector?

How to visualize the vector space?

How to make them more appealing ?

I made a small project of sum and soustraction based on wikipedia based word2vec in cli:

Using two input of the user, it tries to find the following word if you add the semiotic meaning of both word. Thus, it does the revert operation subtracting the two words.
