What is Bubble Chart?
A bubble chart is a variation of a scatter chart in which the data points are replaced with bubbles, and an additional dimension of the data is represented in the size of the bubbles. Just like a scatter chart, a bubble chart does not use a category axis — both horizontal and vertical axes are value axes.
In Bubble Chart, the higher the value of the data point, the bigger will be the bubble, and be seen at the top of the chart. Similarly, the lower the value of the data point, the smaller the bubble and be seen at the bottom.
Some of the common benefits of the bubble charts are:
The Bubble Charts can help analyze the effect of High CPC rates on specified ad placements, clicks, and website conversions and display significant improvements over time when supplied with real-time data.
The Bubble Chart can help determine the density of specific keywords and display the most searched or least searched keywords based on the space the bubbles are occupying on a chart.
Advertisers can use bubble charts to track the effectiveness of advertising and promotions.
Sales and marketing experts can use bubble charts to display their sales insights rather than a list of bullet points or tables to describe the entire metric.
