These tools allow you to translate raw data into different visual contexts. One such context is a bubble chart. But what is a bubble chart? In a nutshell, it is a great charting method for analyzing three or more quantitative variables.\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400\">This article provides a complete guide to bubble charts.

Below is a table containing three numeric parameters: Equities, Age of Investment, and Return on Investment (ROI),\u00a0<\/span>\r\n\r\n&nbsp;\r\n<table>\r\n<tbody>\r\n<tr>\r\n<td><span style=\"font-weight: 400\">EQUITY<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">AGE OF INVESTMENT (YEARS)<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">RETURN ON INVESTMENT (%)\u00a0<\/span><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><span style=\"font-weight: 400\">A<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">6<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">100<\/span><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><span style=\"font-weight: 400\">B<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">1.5<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">20<\/span><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><span style=\"font-weight: 400\">C<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">4.5<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">75<\/span><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><span style=\"font-weight: 400\">D<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">7<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">70<\/span><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><span style=\"font-weight: 400\">E<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">8<\/span><\/td>\r\n<td><span style=\"font-weight: 400\">20<\/span><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nIf the objective is to determine the relationship between all three parameters, how can we do that effectively and quickly? A visual representation of the above data using a bubble chart in one of the <a href=\"https:\/\/www.fusioncharts.com\/blog\/what-are-the-best-javascript-charting-libraries\/\">best JavaScript chart libraries<\/a> is shown below.\r\n\r\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-20612 size-full\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/2022\/07\/Screenshot-25.png\" alt=\"Sample bubble chart created using Fusioncharts\" width=\"709\" height=\"460\" srcset=\"\/blog\/wp-content\/uploads\/2022\/07\/Screenshot-25.png 709w, \/blog\/wp-content\/uploads\/2022\/07\/Screenshot-25-300x195.png 300w\" sizes=\"auto, (max-width: 709px) 100vw, 709px\" \/>\r\n\r\n<span style=\"font-weight: 400\">The X and Y axes denote Age of Investment and Return on Investment, respectively. The investment size is the third variable, represented by the bubble plot&#8217;s area. From the chart above, A has the largest ROI and the largest investment size as well.\u00a0\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400\">Representing these variables in a bubble chart lets you infer not only for one equity, but also analyze relative to another using their distinct positions. This insight is only easily obtainable by visually examining the data through a bubble. It doesn&#8217;t end there; the bubble chart also allows for deeper analysis. Below is the same chart divided into four quadrants.\u00a0<\/span>\r\n\r\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-20613 size-full\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/2022\/07\/Screenshot-26.png\" alt=\"Bubble chart divided into four quadrants\" width=\"606\" height=\"454\" srcset=\"\/blog\/wp-content\/uploads\/2022\/07\/Screenshot-26.png 606w, \/blog\/wp-content\/uploads\/2022\/07\/Screenshot-26-300x225.png 300w\" sizes=\"auto, (max-width: 606px) 100vw, 606px\" \/>\r\n<h3><span class=\"ez-toc-section\" id=\"Quadrants\"><\/span>Quadrants<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">Depending on the parameters, each quadrant can represent different readings for you. For example:<\/span>\r\n<ul>\r\n \t<li style=\"font-weight: 400\"><b>Quadrant 1<\/b><span style=\"font-weight: 400\"> &#8211; <em>Lucrative investments<\/em>: High ROI in a short investment period. Depending on the type of equity, these quadrants are sometimes unsustainable.<\/span><\/li>\r\n \t<li style=\"font-weight: 400\"><b>Quadrant 2 <\/b><span style=\"font-weight: 400\">&#8211; <em>Good investments<\/em>: High ROI in a long investment period. Widely acceptable mode of investment. Making further investments in the equities in this quadrant wouldn&#8217;t be a bad idea.\u00a0<\/span><\/li>\r\n \t<li style=\"font-weight: 400\"><b>Quadrant 3<\/b><span style=\"font-weight: 400\"> &#8211; <em>Below average investments<\/em>: Long investment period, yet low ROI. You wouldn&#8217;t want further investments in equities in this quadrant.\u00a0<\/span><\/li>\r\n \t<li style=\"font-weight: 400\"><b>Quadrant 4<\/b><span style=\"font-weight: 400\"> &#8211; <em>Average investments<\/em>: Average ROI in a short investment period. Equities in this quadrant could be great for low short-term yields.\u00a0<\/span><\/li>\r\n<\/ul>\r\n<span style=\"font-weight: 400\">While this example uses only five equities, in reality, investments could be in the hundreds or thousands. In this case, mental divisions like this are very helpful in making informed business decisions.\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400\">You can access other bubble charts&#8217; live examples in our <\/span><a href=\"https:\/\/www.fusioncharts.com\/charts\/bubble-scatter-charts\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400\">chart gallery<\/span><\/a><span style=\"font-weight: 400\">.<\/span>\r\n<h2><span class=\"ez-toc-section\" id=\"When_Should_You_Use_A_Bubble_Chart\"><\/span><span style=\"font-weight: 400\">When Should You Use A Bubble Chart?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400\">Scatter plots and bubble graphs are quite similar in that you can depict relationships between numeric variables using both. However, the addition of a bubble area allows for comparing the third variable. A bubble chart is best when the goal is to determine the relationship between three numeric variables.\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400\">It would require multiple scatter plots to gain the kind of insights possible with a bubble chart. Even then, gathering insights from multiple charts can result in a disjointed analysis.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Below are some bubble chart use cases:<\/span>\r\n<ul>\r\n \t<li style=\"font-weight: 400\"><strong>To determine the relationship between promotional expenses, footfall, and revenue for retail stores over time. <\/strong>You can represent the daily footfall and promotional expenses on the X-Axis and Y-Axis, respectively. At the same time, the plot area would denote a retail store&#8217;s revenue generated over a period of time. <span data-preserver-spaces=\"true\">This chart can help determine the success or failure of store promotions.<\/span><\/li>\r\n \t<li style=\"font-weight: 400\"><strong>To determine the relationship between CPC, clicks, and conversions in PPC campaigns. <\/strong>A bubble chart represents a perfect way to check if increasing your ad spend on CPC leads to higher clicks and, ultimately, more conversions.<\/li>\r\n \t<li style=\"font-weight: 400\"><span style=\"font-weight: 400\"><strong>Word Graphs.<\/strong> Businesses and marketing agencies could use Word Bubble Charts to identify the best keywords, tags, or hashtags. Examples include: identifying the most searched queries in a particular industry for 2022, or the most used hashtags in fashion and cosmetics on Instagram.<\/span><\/li>\r\n<\/ul>\r\n<h2><span class=\"ez-toc-section\" id=\"Which_JavaScript_Chart_Library_is_Best_For_Creating_Bubble_Charts\"><\/span><span style=\"font-weight: 400\">Which JavaScript Chart Library is Best For Creating Bubble Charts?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400\">Now that you know what a bubble chart is, how can you create one, and what is the best solution for drawing bubble charts?\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400\">Firstly, you need to choose the right JavaScript chart library.
