Scatter plotting and bubble charts are analytical tools that are used in different business, marketing or any data analyses scenarios. They help compare data across different variables; however, there are certain commonalities as well as differences between these two chart forms.
One of the similarities is that both charts have circular forms that are used on a chart or an excel sheet instead of lines or columns.
There are two main differences between scatter plots and bubble graphs. In scatter plotting, the circles or dots do not have any width or size aspect; they can be mere dots or circles but they represent two variables. On the other hand, bubble graphs are essentially three-dimensional graphs. The bubbles and their sizes and volumes are not ad hoc but they represent the third parameter.
Hence, if a scatter plot represents sales amount and profit, a bubble chart can include a third parameter that could be a sales order quantity as represented by the bubble sizes.
