Radar Chart Maker: Uses, Advantages, and Best Practices

What is a Radar (Spider/Web/Polar Bar) Chart?

Suppose you were asked to rank your favorite beer on 8 aspects (Sourness, Bitterness, Sweetness, Saltiness, Yeast, Hop, Malt and Special Grain) and then show them graphically, you might use a Column Chart for it.

But when there are a large number of variables (8 in this case), the Column Chart might look cluttered. In such scenarios, try the Radar Chart instead!

A Radar Chart, also called as Spider Chart, Radial Chart or Web Chart, is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. (Source: Wikipedia)

Each of the 8 aspects of our beer example form individual axes which have been arranged radially around a point. The value of each aspect is depicted by the node (anchor) on the spoke (axis). A line is drawn connecting the data values for each spoke. And thus you get your Radar Chart showing all your data values at one go!

So much for one beer—you may wonder! Now imagine you have 2 beers to compare.

The 2 beers are ranked on each of the 8 parameters. The color coding for each beer helps to visually correlate and contrast the beers over its diverse aspects. If you like your beer bitter, the chart gives you an indication that maybe it's time you switched to Beer B (as Beer B has a higher rank in bitterness to Beer A).

Where can Radar (Spider) charts be used?

Now that you have got a hang of the Radar chart (sometimes also referred to as the Spider Web Diagram), let’s keep our beer mugs aside for a while and see some of the uses of radar charts and their business applications.

Complex Comparisons

These charts enable easy comparison of different concepts and products in a single diagram. Color coding helps differentiate entities, making evaluating and comparing them easier for insights. The simple layout allows for quickly creating complicated, multivariate data displays and organizing essential data and actionable insights logically.


Compared to other chart types, radar charts are more versatile, allowing users to visualize data related to many situations with multiple data sets smoothly and seamlessly.


Radar charts help understand how a concept's value changes over different parameters, enabling comparisons across services and products. They can be used to plot variants and analyze a product's market performance over time. They are also useful for skill analysis, such as assessing team members' problem-solving ability, communication, punctuality, technical understanding, and ability to meet deadlines.


Radar charts provide ample information clearly in one place, allowing for real-time decision-making. They can be used to evaluate critical business data or make prompt decisions that positively influence company productivity and performance.

Other Uses

Thinking of other uses of Radar chart maker? These are also used to visualize complex data sets and spreadsheets, playing a pivotal role in analysis, research, sales, and marketing for businesses across industries.

Skill Analysis of Employees:

A Radar chart can come in handy during the appraisal and review process.

HR managers can visualize employee performance data, based on rankings given by their respective seniors, on a single chart. This chart (commonly know as the Employee Chart) can also be used to plan employee training by grouping employees who lack a particular skill set (low in rank) and then designing suitable remedial procedures for the group.

Advantages of Spider Chart

  • Radar charts, also known as spider chart maker, offer several advantages:

Multifaceted Data Exploration

They excel at displaying and comparing data with multiple variables (multivariate data) in a single visual format. This eliminates the need for separate charts for each variable, condensing the information into one central point with axes radiating outwards. This allows viewers to easily identify relationships and trends between different variables.

Relative Comparison

Radar charts show different entities' relative strengths and weaknesses across various dimensions. Users can plot data points on different axes and connect them to see which variables have higher or lower values for each entity. This comparative view aids decision-taking processes, like evaluating products, strategies, or candidates.

Profile Illustration

Spider charts are well-suited for illustrating profiles or patterns of individual entities. Imagine comparing the skills of several employees across various competencies. Each individual's skill level can be defined by a line on the chart, forming a unique shape that visually shows their weaknesses and strengths. This approach helps in readily identifying individuals' areas of expertise.

Disadvantages of Spider Chart

  • Spider charts, despite their visual appeal, have several disadvantages:

Comparing Values is Difficult

It's difficult to judge the lengths of lines on a spider chart accurately. While people can see which line is longer or shorter, quantifying the difference is challenging. Adding concentric circles may help, but consider using a line graph.

Potential Data Distortion

When you fill the area between data points on a spider chart maker, it can visually distort the data. The shaded area can create a misleading impression of size and positive performance. For example, on a chart with a maximum value of 100, a filled area representing 90 appears much larger than an area representing 82, even though the difference is only 8%.

False Inferences of Relationships

The close proximity of variables on a spider chart can lead viewers to infer connections between them mistakenly. For example, on a chart comparing brownie characteristics like texture and chocolate flavor, their placement might suggest a relationship, even though they are independent attributes.

Product Comparison:

Compare between two or more products over a range of characteristics using a Spider Diagram.

Let's say you want to compare between 2 mobile phones over features like Battery, Camera, Display, Memory and Brand. Get to know which mobile is better when it comes to your most desired feature. Competitive radar charts have multiple use cases. Competitor analysis using radar charts lets you find unique opportunities to close the gap with the competition.

How to Interpret a Spider/Radar Chart?

The center of the chart represents the origin, with data points plotted outward from the center. To interpret the graph, start by locating the center. Look for the origin point where all data points are equal; this indicates similarities among the data points. When data points are closer to the center, they share more similarities. Conversely, they indicate differences when data points are farther from the center. This chart type is commonly used to compare points against a baseline or to illustrate changes in an item over time.

Best Practices for Creating a Radar Chart

While radar charts offer a unique way to visualize data comparisons, their effectiveness hinges on mindful design. Here are the best practices to follow:

Restrict the Number of Variables

With too many variables, radar charts can quickly become cluttered and confusing. Aim for 5-7 variables to maintain clarity and ensure viewers can easily grasp the information presented.

Maintain Consistent Scaling

Ensure all axes utilize the same scale. If one axis ranges from 0 to 100, the others should follow suit. This prevents misinterpretations due to varying scales that can distort the data's visual representation.

Avoid Data Overlapping

When multiple data series overlap, it becomes difficult to distinguish and compare them effectively. To differentiate between series, utilize distinct visual elements or colors. Additionally, consider adjusting their positioning along the axes to minimize overlap.

Provide Context and Interpretation

Always explain the importance of patterns, trends, and differences that the radar chart reveals. With proper context, the audience might understand the information presented.

Embrace Transparency

If data series do intersect, consider utilizing transparent or semi-transparent fill colors. This allows viewers to see overlapping regions more clearly without sacrificing clarity.

Enhance Clarity with Data Labels

Include data labels at the end of each axis, providing the precise value represented by each point. However, ensure these labels do not clutter the chart and obstruct the overall visualization.

Normalize Data for Accurate Representation

As radar chart maker represent data across various axes, it's essential to normalize your data. This means scaling the values to a consistent range to avoid any single variable overshadowing the chart due to its big scale.


Radar or spider charts offer a visually appealing way to compare data across multiple variables. They excel at displaying complex data sets and highlighting individual strengths and weaknesses. However, radar chart maker effectiveness depends on mindful design and interpretation. Remember to limit variables, maintain consistent scaling, and provide context for clear and accurate communication.
