Different Types of Bubble Charts

Brainstorming is important to focus on sheer quantity, defer judgment about the quality of ideas, and encourage new ideas. That’s why bubble charts are very crucial in brainstorming ideas while taking notes, collaborating and presenting more effectively. However, what are the different types of bubble charts that you need to make? Consider reading the details as follows:
1. Simple Bubble Chart
This is the most basic bubble chart type as it portrays only the first three numerical data columns in a specific table. For example, you are working on 3 variables using the horizontal axis, y-axis, and the size of the circle. Actually, there exist some possible differences when it comes to utilizing the values in generating the chart from the ones depicted in a table. Develop different variations of simple bubble charts if you are using the random number generator function in Excel.
2. Double Bubble Chart
Do you need to make comparisons and contrasts on specific things such as artifacts, events, ideas, individuals, and places? If yes, then you will need to create a double bubble chart or map. A double bubble chart starts with two adjacent central bubbles in which the two ideas are indicated. Then, bubbles are incorporated between the two ideas or concepts to capture the common elements between them, while additional bubbles are included on the outer extremity of the two original ideas to capture varying elements. Educators, teachers, instructors, and teachers can utilize this bubble chart variation to assist their students in gaining clear insight about the idea of categories or certain kinds of descriptors.
3. Bubble Scatter Chart
If your data contains three data series that each have a set of values, use a bubble scatter chart in order to present data points through bubbles with an additional dimension of the data illustrated in the size of the bubbles. Often used to display financial data, bubble charts are crucial to visually highlight specific values. To construct a bubble scatter chart, arrange your data in rows or columns on a worksheet and list the x values in the first row or column and list the corresponding y values and bubble size (z) in adjacent rows or columns.
4. Map Bubble Chart
Typically used on maps for geographical sciences, a map bubble chart is essential to represent a geographical location on the map. For instance, using a map bubble chart will guide you to plot a map so that you are able to identify specific places for your research work. To make sure that each location is properly recorded, the x and y axes will be plotted through the latitude and longitude of the places while the bubble size should tally according to the size of the graph on which it is being plotted.
When to Use Bubble Charts
To construct the right bubble chart which can provide your needs or offer potential solutions to specific issues and concerns, it is important for you to be familiar with the circumstances that are openly aligned with the usage or purpose of a certain document. Doing this will help you and your group members to share and collaborate extensively, allowing each one of you to record meaningful ideas, plan, and manage tasks, activities and meetings, and discuss the fundamental matters with the overall team.
