The answer will depend on the information conveyed by each graph. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Any graph can be used to determine something!
You would not use a graph to determine one person's height at a single point in time. You could use a line graph to track the height of a person over time. You could use a histogram to determine the heights of lots of people at one time.
When your data is in percents, a common type of graph to use is a pie chart. This type of graph is particularly useful for showing the distribution of a whole, where each category represents a percentage of the total. A pie chart is visually appealing and easily highlights the proportion of each category.
Find the shortest bar and read what state it represents. (In a bar graph, the length of each bar is proportional to the number it represents. )

A bar graph is produced to indicate the quality of each answer.
To determine the number of cycles in a graph, you can use the concept of Euler's formula, which states that for a connected graph with V vertices, E edges, and F faces, the formula is V - E F 2. By calculating the number of vertices, edges, and faces in the graph, you can determine the number of cycles present.
When you want to illustrate shares or percentages of the total for 4-9 main categories. A pie graph with more categories if OK, if each is very small, but otherwise you have visual clutter, and the pie graph does not readily impart information.
A line graph is best.
The answer depends on what the bars show. If they are the percentage shares of total votes that were cast for one party (or candidate) then you cannot.
A distance time graph is important because it helps determine the speed of a person or object. The use of the graph helps to easily interpret the results.
