Know it All about Bubble Chart

Part 1: What is a Bubble Chart?

Also known as the bubble graph, bubble charts are an extension of the scatter plot and proportional area chart. They are a popular multivariate data graph drawn on a 2-D scale but can represent the 3-D values. Like a scatter plot, these graphs use the Cartesian coordinate system to represent the values.

However, bubble charts have bubbles instead of dots for representing the values. To represent a data series, the size and location of the bubbles is altered. In some cases, color may be changed to represent the fourth value. Due to this application, these charts are popular in engineering, finance, medicine, economics, etc.

Part 2: Pros and Cons of A Bubble Charts

Bubble charts are useful graphs that are a popular choice for representing multivariate data. However, this chart has its shortcomings too. Let's see both of them briefly.


  1. Displays three variables on a 2-D page.
  2. Provide a quick overview and easy comparison between the two similar projects.
  3. By assigning colors to the bubble, we can also represent a fourth value.
  4. Illustrates extensive data in a simple and fun way that is easy to read and understand.
  5. Can easily depict the relationship between three values and their changing trend.


  1. Too much information and bubbles can clutter the graph and make it difficult to understand it.
  2. Bubbles may overlap over each other, causing a problem in differentiating them and the values.
  3. It is difficult to extend and display the bubbles that have a negative or a zero value.

Part 3: When to Use A Bubble Chart

With a list of advantages on its profile, Bubble charts are a handy graphical tool used in many cases. Let's have a look at some of these scenarios.

  1. Most commonly used when you want to represent 3-D data and the basic visual tools like scatter plots, bar graphs, column charts, line graphs, etc., are incapable of it.
  2. When dealing with multiple data sets with hundreds of values, the circle will help you represent the different data values. In contrast, the diameter of the circle corresponds to the value.
  3. Often used when representing and comparing the economic or social conditions of an area, product line, or population.
  4. They are used to present the financial data and help in following the trend. Analyzing the trend helps in highlighting the cause of a problem.
  5. Used for scientific and research purposes to show the relationship between three entities and how changing one affects the other two.
  6. They are also employed in Architecture and applied to the first sketch created with bubbles.
  7. They are extensively used by software engineers, politicians, mathematics, analysts, scientists to illustrate the change in trends and data values.

Part 4: Different Varieties of A Bubble Graph

Bubble Charts are dynamic and the most versatile kind of charts to exist. They further differentiate into different types. Let's check them out.

1. Labeled Bubble Charts

These are simple charts with few data plots. The only unusual thing is that every individual bubble is labeled. This helps in clarifying the name and makes it easier to refer to a specific bubble on the chart. However, the data in the labeled charts are kept limited; otherwise, it would get cluttered and incomprehensible.

2. Numeric Color Variable Bubble Charts

This is also a simple and minimalist chart where numbers are encoded with colors. For instance, the example below illustrates a chart showing concern about several countries' food. Some bubbles are colored grey, while the others are colored light blue.

The areas with a darker shade represent a higher intensity of concern, whereas the light blue regions indicate the absence of concern. This is how you can assign colors to the bubble and illustrate their intensity without mentioning any numbers.

3. Bubble Map

Bubble maps are also known as cartograms and are an extension of the scatter plots. They are a simple yet innovative idea of representing geographical locations. The bubbles are overlaid on a map and represent the latitude and longitudes coordinates.

4. Bubble Clouds

Also called the circle packing charts, bubble clouds look like bubble charts from a surface view. The circles are tightly fitted and packed together to only represent one value. They may be clustered together in a haphazard position or ordered according to their value. Often the bubbles are also encoded with colors for a better comprehension of the graph.

  • Now, let's see some of the creative bubble charts templates from Edraw and see what these charts can be used for.
  • Height and Weight Comparison

    This is a simple bubble chart that compares the height and weight of males and females. The three variables here are weight, height, and gender. Axes have been sketched for the average values, and the colors are assigned to each sex. This type of graph enables us to assess that males usually tend to grow higher while females are fatter.

    Sports and Games Chart

    This is another colorful and innovative template that allows us to compare different types of sports. It mentions the percentages for each game and draws three different types of bubble diagrams. It can be seen that the bubbles differ in their diameter due to the difference in values. Such diagrams are of great help when you want to make a thorough comparison.
