The Scatter plot is a temporal plot used for data visualization. Scatter plots are usually used when we want to display the relationship between two variables. They are widely used since they provide a compact data visualization. There are some points that must be kept in mind while using a scatter plot. Trend lines help to visualize the data to a great extent on a scatter plot but you should use only 1 or 2 trend lines to avoid confusion. Also, the y-axis should always start from 0.
