Graph
A concrete graph is a graph that records, organizes, and displays data using objects on a mat with appropriate labels.
Numerical data are organized by a graph.
A scatter diagram.
You're probably thinking of a stem-and leaf plot, or maybe a histogram.

The difference between a graph and a diagram is as follows: a diagram is a chart which shows a drawing and a graph is a graph with lines or bars indicating something specific in numbers.
A stem and leaf plot is not a graph, but it is a table. You can turn it into a graph, a histogram, but it is simply a table that organizes your numbers.

A Data Graph is a just a graph of data :) -Hope This Helps =D
