At least three items -- the title or caption, the labels for the horizontal and vertical axes, and scales for these axes (clearly mark where the origin is). You should add legends if more than one curve exists in the graph. A text box alerting the reader what to look for will be a plus. See the related link for an example.
====================================
A key can make it easier to interpret the data sets that each part of the graph represents, especially if there is no room in the graph area for labels.

When constructing a graph one of the most important factors to consider is clarity. Clarity includes elements such as the titles labels and scales of the graph. The titles should clearly indicate the type of data being presented the labels should provide context for the data and the scales should be accurate and easy to read. Additionally the graph should be visually appealing using colors and fonts that are not too overwhelming. Titles: Clearly indicate the type of data being presented Labels: Provide context for the data Scales: Accurate and easy to read Visual Appeal: Colors and fonts that are not too overwhelmingTaking the time to ensure clarity and visual appeal in a graph will help to make the data easier to understand and interpret.
Don't make graphs misleading!As for the answer: different scales, leaving out points, drawing extra lines with no meaning, confusing labels, ...Most graphs you see online are misleading, few are really good.

axis labels are x and y while bar graph labels explain what the graph is representing.

A concrete graph is a graph that records, organizes, and displays data using objects on a mat with appropriate labels.
Yes because you need the data on the right and across the bottom to make the graph
The answer depends on what the graph is meant to show. The first step would be to read the axis labels.

I suggest you go to your math book and look at an example of graphs. Basically, it is a box with labels on the bottom (horizontal axis) of the box representing the items you are graphing and along the vertical axis you will have data. You will put in bars of different colors to represent the data corresponding with the labels. A double bar graph would be two of these.
