It is an end-on representation where the molecule is viewed along the bond of interest, a projected bond. The atom farther from the observer is represented by a circle, and the atom closer to the observer is denoted as the center of the circle.

A Newman projection looks at the conformations about a pair of carbon atoms. They can be any two carbon atoms you choose. In this case, they wanted to show the relation between the methyl group on C-1 and the groups on the neighbouring carbon atoms (C-2 and C-6). They simply chose to look at the C-1, C-2 bond.

Here are the pictures of the eclipsed conformations from the video, and our goal is to pick the least stable, but just for practice, let's try drawing all of them as Newman projections. So we'll start with the one on the left here, and we're staring at C2, so that's C2, which we represent by a point.

To show stereochemistry, we must use wedge-dash formulas. These formulas give the stereochemical information. But it is easiest to compare structures using Fischer projections, because they are always written in the same way. If we make the wedge-dash formula vertical with C-1 at the top, it becomes structure B above.While organic chemists prefer to use the dashed/solid wedge convention to show stereochemistry, biochemists often use drawings called Fischer projections and Haworth projections to discuss and compare the structure of sugar molecules.
