I'm new here so if I make any mistakees I apologize in advance. Looks to me that maybe the Dharma logo is an outline of the island and the 6 points are each station or hatch. The bottom one in the screencap being the Swan(I like the "you are here" sign). All of them pointing toward the central point. Question is what is this point. Also the Swan point seems to have a scetch or an outline of the hatch. The others don't seem to have.
