Data is a commodity. Just like any other commodity, the value placed on data cannot be over-emphasized. This makes data the most valuable asset in the world. After all, data gives birth to useful information. In this blog you will learn what is a Chord Diagram? And How to Create Chord Diagram in few steps with coding.
In Data visualization, the use of the chord diagram is quite popular and attractive to many digital marketers and data analysts. What then is a Chord diagram?
A chord diagram represents the flows or connections between entities known as nodes. A typical chord diagram has a standard circle. The entities or elements are then arranged as points around the outer circle.
The relationships and connections between the entities are then shown using smaller arcs and curves in the inner circle. The connections between these entities are used to display that they share something in common.
Let me show you how to create Chord Diagram with the help of an example. Now, let me show you how Jasmine used ChartExpo to analyze hospital data.
Jasmine is a data analyst who just got contacted by the human resource manager of Richie Hospital. Richie Hospital was surveying their teams. They wanted to see how well their teams have been behaving with the patients and visitors at the hospital.
Survey forms were printed to rate individual teams. Every team had a specialized form for them to be rated by patients and visitors who had contact with them. The patients and visitors would therefore drop their comments concerning the specific team.
This survey was conducted three times within one year. Jasmine received the survey answers as data. She was then assigned the task of analyzing and visualizing the data. After inspecting and organizing the data, she was torn as to which data visual would be suitable for the representation of her data.
After much thought, she came up with the idea of dividing this survey into three different main categories. Each of these categories will then have subcategories. After she sorted the main categories according to the number of respondents per team, she got stuck. She had no coding experience and she was running out of time.
She then turned to research where she found ChartExpo as her best option to analyze data on Google Sheets. After installing the add-on, here is what she did. She prepared the data in a table:
| Topic | Subtopic | ChordColor | ChordDarkness | TopicValue | SubTopicValue |
|---|---|---|---|---|---|
| Anesthetic | Chaplaincy | Positive | 10 | 36 | 7 |
| Anesthetic | Critical Care | Positive | 9 | 36 | 5 |
| Anesthetic | Safety | Positive | 9 | 36 | 12 |
| Anesthetic | Administration | Positive | 10 | 36 | 4 |
| Anesthetic | Elderly Services | Positive | 6 | 36 | 4 |
| Anesthetic | Gastroenterology | Positive | 6 | 36 | 4 |
| Emergency | Cardiology | Negative | 6 | 12 | 7 |
| Emergency | Gynecology | Neutral | 1 | 12 | 5 |
| Hematology | Infection Control | Negative | 2 | 30 | 4 |
| Hematology | Maternity | Negative | 3 | 30 | 4 |
| Hematology | Nephrology | Negative | 1 | 30 | 1 |
| Hematology | Neurology | Negative | 1 | 30 | 12 |
| Hematology | Orthopedics | Negative | 6 | 30 | 9 |
| Pharmacy | Physiotherapy | Negative | 3 | 8 | 4 |
| Pharmacy | Radiology | Negative | 1 | 8 | 4 |
| Radiotherapy | Renal | Negative | 1 | 20 | 8 |
| Radiotherapy | Urology | Positive | 2 | 20 | 10 |
| Radiotherapy | Renal | Positive | 1 | 20 | 2 |
Then, she opened her Google Sheets and organized her data in it.
She filled the column with the header names and values as:
Which represents different departments of hospital.
Which represents different area of expertise or incident name.
How the sentiment will appear, green for positive and red for negative.
This represents how many total reviews or values came under the value first column i.e Topic. E.g Emergency got 7 Negative and 5 Neutral that is why 12 is coming for this data. In visualization length of blue color is being represented by this value.
Final numerical value which represents number of counts of specific feedback.
Here is how she drew her chart:
Jasmine clicked first on ‘Sentiment Analysis charts’ and then on ‘Chord Chart’. Then, she selected her Sheet Name.
Next, she clicked on ‘Add new metric’. She then selected the column in which she had inputted numerical values.
She then clicked on Add new dimension and selected the ‘Topic’ column. Afterwards, she added the ‘subtopic’ column and the ‘sentiment’ column.
She got the following result.
Jasmine looked at her chart and was able to completely capture the thoughts of the patients and visitors at Hospital. The chart showed the general opinions of the people towards the teams at the hospital.
For the chart, she decided to use blue for service-related results. She used green to depict positive reviews. She then used red color to depict the negative reviews and gray for neutral reviews.
She saw that the Anesthetic department had total 36 reviews and the administration department had 4 positive reviews. From the chart, we can also observe that the Cardiology department had 7 negative reviews under the emergency.
From the respondents at the Pharmacy, there were 8 negative reviews. The Radiotherapy Department also had 8 negative reviews for renal and 2 positive whereas urology had total 10 positive.
She used the grey color to show neutral reviews.
You can see that this data visual self describes its insights. A person with no idea about data visualization can understand this chart.
Colors can be used to group the data into different categories. This helps in making comparisons and distinguishing the different groups that the entities belong to.
It also provides you a way to visualize your dataset in an aesthetic, appealing, and informative manner. It will also show you the direct relationships between different element categories.
The ability to gather, organize, understand, process, extract value from, visualize, and communicate data is a skill that is already so valuable. It is then easy to predict that this skill will be the next big thing in the coming years.
According to research, the human brain is not equipped enough to comprehend raw and unorganized information. Hence, the need for data visualization. Before we go too far, let us see what data visualization really is.
Data visualization is a graphical representation of information and data, which can be achieved by using visual elements like charts, graphs, tables, and maps. You will therefore agree with me that we need charts to properly analyze and communicate data findings. This will help you to identify patterns and trends in order to gain insights and to enable better decision-making.
The use of graphical representations to visualize your data will make your clients glued to your brand and think the best about you. Visualization tools will give you access to user-friendly and beautiful features that represent your data in an impressive and expressive way.

Most times, we are all bored of words that are written in black and white. Data represented with visuals will immediately attract more attention and are easier to comprehend. With the help of descriptive graphics and dashboards, difficult information can be obvious and understandable.
This is because most people are visual learners. Hence, for your data to be clearly understood by your audience, which may be your colleagues, partners, or clients, all boring charts should be turned into adorable and attractive graphics.
