Keywords
Pictogram - A pictogram (pictograph) is a graph consisting of pictures to visually represent the frequency of objects or groups.
Bar chart - A bar chart (bar graph) is a graph consisting of bars visually representing the frequency of objects or groups.
Scatter graph - A visual representation for bivariate data. It can be useful when determining the nature of the relationship between two variables

Common misconception
You always need to start the axis of a scatter graph at (0,0).
The axis of a scatter graph should use a scale that makes the points as clear to see as possible, without distorting the shape of the data.
