A graph is a way of representing connections between places.
Mathematically, a graph is a collection of nodes and edges. Nodes are
locations that are connected together by the edges of the graph.

I need graph data for the city of Hickory, North Carolina. How can I
have/buy those data ? Please provide links where I can buy for
reasonable prices. I need this for my project.

What kind of data do you want?

There are probably Census data (population, income, etc) readily
available for Hickory, NC.  Would that do the trick?

Graph not Graphics. A graph is a way of representing connections
between places. Mathematically, a graph is a collection of nodes and
edges. Nodes are
locations that are connected together by the edges of the graph. It is
for making a map. For example, distance between intersection A and
intersection B.

Actually a graph is a diagram (as a series of one or more points,
lines, line segments, curves, or areas) that represents the variation
of a variable in comparison with that of one or more other variables.

The question is what variables are you interested in?  Do you want the
distance between buildings?  Street Intersections?  What?

Streets and intersections are good, and enough for my project. But, if
there is more complete data (between buildings) for the same price, it
would be great.

I think the information you're requesting may be impossibly large.  A
list of the distances between each interesection and all other
intersections would be huge.  Hickory appears small, but I think if
you included buildings the list would be impossibly huge.

The best I can come up for you is this:

It's not a list, but it is a zoomable map that contains a lot of info.

If you need distances between certain addresses or intersections and
they aren't "as the crow flies" I'd use google maps.
