Probably where both variables are continuous.
A histogram graph displays continuous data. The data is displayed in ordered columns. Example of data that can shown by a histogram graph is time, inches, and temperature.
when you are comparing
A pie chart, also known as a circle graph, shows categorical data using percentages. A bar graph shows categorical data using whole numbers.
first a line graph shows data that is continuous so something that like weather or rain fall
If scales are too big, the right picture to represent an item displayed on a graph is not used, or if the graph doesn't start on zero, all are ways the data can be misrepresented!
It is true.

Parts of a whole.

A circle graph, or pie chart is best used for showing parts of a whole.

I believe trends in data should be presented in a graph.

data
A graph that shows little pictures. If I had a graph about cats I might show cat faces in a picto graph as a form of data, so if there were 10 cats to be displayed in the graph it would be with cat faces and not bars or lines.
