2. Key Chart Types for Comparing Data with Relative Percentages
Several types of charts are specifically designed to compare data using relative percentages. These charts excel at showing the proportion of different categories within a whole, making them ideal for understanding market share, budget allocation, or survey results. Let’s explore some of the most effective options.
2.1 Pie Chart
A pie chart, also known as a circle chart, is a common data visualization technique used to compare the sizes or percentages of different categories within a whole dataset. Each slice of the pie represents a category, and the size of the slice corresponds to the percentage of that category in relation to the whole. Pie charts are particularly useful when you want to illustrate part-to-whole relationships and highlight the relative importance of different categories at a glance. They are widely used in marketing, finance, sales, and sports for data visualization.
Primary Use Cases:
- Showcasing part-to-whole comparisons.
- Illustrating proportions to identify the most and least important categories quickly.
- Representing a limited number of categories dealing with percentages or numbers.
2.2 Doughnut Chart
The doughnut chart is similar to a pie chart but features a hole in the center. This central area can be used to display additional information or simply for aesthetic purposes. Like pie charts, doughnut charts are effective for visualizing the proportion of different categories within a whole. The visual structure of a doughnut chart can sometimes make it easier to compare the relative sizes of different segments, as the focus is on the arc lengths rather than the area of the slices. Doughnut charts are commonly used in presentations and reports to present data in an engaging and easily understandable format.
Primary Use Cases:
- Representing data with a small number of categories.
- Emphasizing the relationship between a central category and its subcategories.
- Highlighting the main categories while still providing a visual representation of the whole dataset.
2.3 Stacked Bar Chart
A stacked bar chart is used to compare the composition of different categories. Each bar represents a category, and the bar is divided into segments, each representing a subcategory. The length of each segment corresponds to the percentage of that subcategory within the category. Stacked bar charts are useful for comparing both the total values of different categories and the relative contribution of their subcategories. This type of chart can be particularly effective when you want to show how different factors contribute to the overall value of each category.
Primary Use Cases:
- Comparing the composition of different categories.
- Illustrating the relative contribution of subcategories within each category.
- Analyzing trends and patterns in the composition of data over time.
2.4 100% Stacked Bar Chart
A 100% stacked bar chart is a variation of the stacked bar chart where each bar represents 100%. The segments within each bar represent the percentage of each subcategory in relation to the total for that category. This type of chart is particularly useful when you want to compare the relative proportions of different subcategories across different categories, regardless of their absolute values. The 100% stacked bar chart is effective for highlighting the percentage distribution of data and comparing the relative importance of different factors.
Primary Use Cases:
- Comparing the relative proportions of subcategories across different categories.
- Highlighting the percentage distribution of data.
- Analyzing the relative importance of different factors.
2.5 Area Chart
An area chart displays quantitative data graphically. It is based on the line chart. The area between axis and line are usually emphasized with colors, textures and hatchings. Commonly one compares two or more quantities with an area chart.
Primary Use Cases:
- Displaying trends over time
- Showcasing the magnitude of change.
- Comparing multiple data series.
2.6 Treemap
A treemap displays hierarchical data as a set of nested rectangles. Each rectangle represents a category, and its size corresponds to the value of that category. The rectangles are arranged in a hierarchical structure, with larger categories containing smaller subcategories. Treemaps are useful for visualizing large datasets with complex hierarchical structures, allowing you to quickly identify the most important categories and their relative proportions. This type of chart is commonly used in business intelligence and data analysis to explore and present hierarchical data.
Primary Use Cases:
- Visualizing large datasets with complex hierarchical structures.
- Identifying the most important categories and their relative proportions.
- Exploring patterns and trends in hierarchical data.
2.7 Sunburst Chart
A sunburst chart, also known as a radial treemap or multilevel pie chart, is used to visualize hierarchical data in a radial format. The chart consists of concentric rings, with the innermost ring representing the root node and each subsequent ring representing a level in the hierarchy. The size of each segment corresponds to the value of that category, and the color can be used to represent additional information. Sunburst charts are useful for exploring hierarchical data and identifying patterns and relationships between different levels of the hierarchy. This type of chart is commonly used in data analysis and visualization to present complex hierarchical data in an engaging and easily understandable format.
Primary Use Cases:
- Visualizing hierarchical data in a radial format.
- Exploring patterns and relationships between different levels of the hierarchy.
- Presenting complex hierarchical data in an engaging and easily understandable format.
3. Other Chart Types for Data Comparison
While the charts above are excellent for comparing data with relative percentages, other chart types are also valuable for general data comparison. These charts may not directly represent percentages but can still provide insightful comparisons between different categories or variables.
3.1 Bar Chart
A bar chart (or bar graph) is the simplest chart type for comparing different categorical data. You can create visually appealing bar charts that can be plotted both horizontally or vertically. These charts consist of an x-axis that represents categories, while the y-axis represents the numerical values. Rectangular bars represent separate categories, presented in different colors to make a visually appealing graph.
Primary Use Cases:
- Illustrating a comparison of variables across different subgroups of data.
- Analyzing and comparing numerical data across large categories or groups.
- Monitoring changes over time, particularly if the amount is significant.
3.2 Histogram
A histogram is a chart created for comparing numerical variables. It outlines quantitative data, such as height, weight, temperature, and length, measured by dividing the data into intervals or bins. In such representations, intervals or bins are represented by the chart’s x-axis, and the frequency of data points in each bin is represented by the y-axis. The rectangular bars are next to each other because their bases cover the intervals; the taller the bar, the higher the frequency.
Primary Use Cases:
- Showing the frequency of numerical data within specific intervals.
- Analyzing whether the process changes from one period to another.
- Dealing with data sets that consist of large numbers of data points.
3.3 Line Chart
A line chart is a visual representation that displays information as a series of data points connected using single or multiple continuous lines. Moreover, the data points depict the trend or pattern for a variable over a second variable for a certain period of time. Typically, the x-axis represents the categories equally, while the y-axis represents numerical measurement values. Line charts are frequently used in business, economics, and finance to illustrate stock prices, sales figures, or survey results.
Primary Use Cases:
- Summarizing trends and fluctuations to make future predictions.
- Illustrating positive or negative trends.
- Providing insights to stakeholders for decision-making through a one-to-one comparison.
3.4 Overlapping Area Chart
This is a mixed version of a bar chart and a line chart. Like a bar chart, it has horizontal and vertical axes to represent data values, and like a line chart, it visually connects data points. The overlapping area chart has data as a series of points connected horizontally using lines from left to right. Below the line, shades of transparent color are used to separate each area. For instance, this type of comparison graphic can showcase the dominance of different wildlife populations among different species before another type gains momentum.
Primary Use Cases:
- Comparing multiple data series and showing the overall trend.
- Having multiple data series with part-to-whole relationships.
- Illustrating a change of trends among different datasets within a graph.
Note: Overlapping multiple data series can lead to complexity and visual clutter. In that situation, use a simple line chart to show data comparison.
3.5 Combo Chart
The Combo Chart, also referred to as the hybrid chart, brings together two distinct chart types into one powerful visual representation. It is a fusion of charts, typically combining elements from both bar and line charts. These charts can be designed using single or two datasets, but both datasets need to share common traits for comparison. For example, imagine your company wants to plot monthly projected vs actual sales numbers; you can demonstrate this using a combo chart.
Primary Use Cases:
- Illustrating a one-to-one comparison between two different chart types.
- Showing both categorical data (represented by bars) and continuous data (represented by lines).
- Displaying complex data patterns that cannot be effectively shown using a single chart.
4. How to Choose the Right Comparison Diagram
Choosing the right chart/diagram can enhance the effectiveness of data visualization, helping your audience digest the valuable insights you wish to present. Here are some best practices to consider when selecting the appropriate charts to compare data:
4.1 Understanding Data Type
