The original graph for this was on the following webpage:
I thought it was a bit cluttered, and hard to grasp.
So, after reading the description under the graph on that
webpage (which describes how to interpret it), and after
scrutinizing it for a while, I come up with my own version,
which (I hope) is simpler to use...
Rather than having all these heavy lines, and lighter
shaded rectangular areas leading up to the lines (with gaps
between the shaded areas and the lines, which I don't really
see any purpose they serve), I used a simple strategically
labeled "area chart" instead.
I changed the labeling in the areas to make it clear that
*any/all* of the lesser resolutions are good up until the
colored area changes, and then one of the resolutions drops
out of the group.
I also changed the wording on the right-side of the graph,
where it describes the change - rather than saying that
"full benefit is visible", I approach it from the other
direction and say that's where the picture becomes grainy
(if you get a bigger screen or get closer to the TV).
Because that's really what you want to know - as you get
bigger screens, or sit closer to the TV, where does each
of the lower-resolution technologies start to look bad/grainy.
Also, I have laid out my annotated text so that it reads
easily from top-to-bottom, left-to-right, since that's
the way most people like to read (at least for English).
I also added light/dotted reference lines, to make it easier to
find where your distance & screen-size fall on the graph.
In addition to the no-nonsense analytical version of the graph,
I also do a "fun" version, where I overlay the graph on top of
an image of a vintage TV screen.
Depending on your audience, you might prefer one over the other.
