Any kind of graph can be used for discrete data.
Yes.
A pie chart :) or a bar graph.
yes
Yes it is. Discrete data is something that's set. Like say you were making a line graph about renting bikes. You can only rent whole bikes there is nothing in between. You shouldn't connect points on a line graph with discrete data but some cases can be argued. Continuous data is usually a measurement that could change like time.
A line graph is not a good way to represent the data as the number of CDs is a continuous variable, but the artists are a discrete, categoric variable. A line graph should be used when both variables are continuous. A bar chart or bar graph should be used when one variable is continuous and one is discrete.
Bar graph.
Yes.
A pie chart :) or a bar graph.
A bar graph works well in this case
yes
A discrete graph.
Almost any kind of graph can be used to show discrete data: You can use a line graph (most economic data), a bar graph (demographics), a pictogram, a pie chart, a scatter plot, radar. Although 3-d charts can also be used, they are very poor at conveying information because of the difficulty in interpreting depth.
A bar graph shows discreet data, but other types can also.

A discrete graph is a type of graph that represents data points as distinct, separate values rather than continuous lines. In a discrete graph, the points are plotted individually, often connected by lines or left unconnected, to illustrate relationships between the variables. This type of graph is commonly used in situations where the data involves distinct categories or counts, such as the number of students in different classes or the results of a survey.
