Introduction to IELTS writing graphs and charts: similarities and differences, with bonus tips

Graphs and charts are some of the most common items in IELTS Writing. So, here’s a post to help you fix some misunderstandings about IELTS writing task 1 which will, for sure, simplify your thoughts and change the way you look at Writing Task 1, particularly, graphs and charts. It will also help you to find out the similarities and differences between different graphs and charts.

Introduction to IELTS writing graphs and charts: similarities and differences, with bonus tips

First, let’s have a look at the concept of graphs and charts in IELTS Writing. We have some common questions regarding this segment such as:

  • What are graphs and charts?
  • How many types are there?
  • What are the differences between them and diagrams?
  • Why are they in IELTS Writing?

And most importantly,

  • Do you need to study each of them separately?

The answers lie in the next few paragraphs.

Graphs and charts are a really great way to understand and define data. Data refers to numbered information. They can be of numerous types like:

  • Prices of sold items
  • Number of people working somewhere
  • Population of a country or place
  • Period of time you work for your company
  • Values/ amounts of export and import
  • Literacy or illiteracy rate in a targeted region
  • Scores/ Grades you make in SAT, GRE, GMAT, IELTS
  • Your yearly exam result in school or colleges
  • Weekly salary distribution of a company or organization
  • The numbered result of a survey or census etc.

The list can go on and on. However, as the graphs and charts are represented in pictures, we can divide them into five main categories.

  1. Line graph
  2. Column graph
  3. Bar chart
  4. Pie chart and
  5. Table

Let’s have a look at the pictures so that it becomes easy for you to recognize them.

  1. Line graph

A line graph contains one or more lines representing a sequential change to some figures in a period of time.

The line graph shows the number of students dropped out from St. Martin’s School from 1999 to 2004.

  1. Column graph

The column graph shows the number of students dropped out from St. Martin’s School from 1999 to 2004.

  1. Bar Chart

A bar chart looks like a column graph, only it represents some items or numbers in a singular time, not in a period of time.

The bar chart shows the types of students dropped out from St. Martin’s School in 2004.

  1. Pie Chart

A pie chart looks like a circular representation of some data. Generally, percentage is given here to different items.

The pie chart shows the types of students dropped out from St. Martin’s School in 2004.

  1. Table

A table at the same time can represent period of time, items, types and numbers.

The table shows the types of students dropped out from St. Martin’s School in 2004, 2005 and 2006.

Explanations of graphs and charts: Now, as we can differentiate between the graphs and charts, the broad question arises. Do we need to study all of them individually? It’s because you know that you need to study different diagrams too. So, there are many other items to cover such as several kinds of diagrams and flow-charts.

The answer for this is that you need not study all the items. Some of them have so many similarities that you don’t even have to touch some of them. You just need to understand the concept of it. It might sound unbelievable. Well, let’s have a look.

Look at the example line graph and column graph pictures above. Look closely. Do they look same to you?

There is nothing different between them except for the pictures. This is because line graph and column graph are actually twin brothers with differences in appearance. How?

Look at the horizontal lines (the straight line in the graphs below from left to right). In both pictures, the horizontal lines are indicating a period of time from 1999 to 2004. Remember, when a period of time or timeline (such as years, months, seasons, decades, centuries, clock-times) is given in the horizontal line, a line graph and a column graph has no difference. You can study only line graph. You just need to write the name according to the rubric or title of the graph.

The same thing goes for the bar chart and pie chart too. They are representing the same data, only in different pictures. Even the first part of the table (data for the year 2004) also shares the same data of the given bar and pie chart. So, there is a good chance for you to skip learning all the types.

Thanks for being with me so far. It means that you are slowly getting the concept.

Now, the trouble comes when you see a bar chart and column graph. It is because they look the same. Well, you need to have sharp eyes here. Remember I told you that horizontal line of the line graph and column graph represents a period of time? Look closely at the bar chart. Is there any timeline here? You can’t see any other time except for 2004 in the title. That’s the difference. A bar chart represents item types whereas a column graph represents a timeline. The usual columns in a bar chart can be both horizontal and vertical. If it’s vertical, it’s easy for you. If it’s horizontal, it gets difficult to differentiate between it and column graph. That’s why; please take a look at the picture below which will surely clarify the differences.
