There are a lot of different types of graphs so it is inevitable that I will miss some but here are the main ones:
Bar / column chart - use if your data is in groups - either categoric (fits into unordered categories such as colour) or split into groups (e.g. 0-10, 10-20, etc.).
Histogram - extension to the bar chart - use if the data is split into groups that are unequal (e.g. 0-10, 10-15, 15-30, etc.).
Scatter chart - use if all of the data is continuous (i.e. can be any value within a range (e.g. time/temperature).
Line graph - extension to the scatter chart - has a line of best fit - use if the two sets of data on the x and y axis are related.
Pie chart - use if you want to show fractions of the data (e.g. that over half of people have one car but that only a quarter have two) - the data must be categoric (described above).

A pie graph is useful for showing percentages. It is great for showing percentages in a survey.
to represent and compare datas to it.
No, it is not an appropriate graph.
For any data that can be best expressed as percentages of a whole, a pie chart or pie graph is appropriate.
You select an appropriate scale.

When determining the appropriate name for a graph, consider the data being represented and choose a title that accurately describes the information displayed in the graph.
The answer depends on what the data are: if you want to compare times before and after practise then a scatter graph may be appropriate. If it is the times in a single experiment then a bar chart for frequencies in time intervals or a histogram may be appropriate.
Meaning of "Is the Scope of the graph appropriate? "
A concrete graph is a graph that records, organizes, and displays data using objects on a mat with appropriate labels.
