What is graph description writing and why is it important?


Graph description is related to the section of findings, where researchers often present their data in graphs, or tables, or charts and provide a description to highlight the major trends. Graph description is a basic and important skill in academic writing.
Steps in writing a graph description Structure of graph description
1. Read the title and labels on the graph as well as the instructions.
  - Note down 2-3 synonyms for key words/phrases
  - Write down introductory sentence, trying not to copy phrases
2. Analyse the information in the graph, looking at the overall trend(s).
  - Write the rest of your introduction, explaining the main trend(s)
3. Plan your body paragraphs (one paragraph for each trend)
  - Draft a topic sentence for each paragraph
4. Choose the most important details that will support your statement(s) or main trend(s).
  - Write the rest of the main body paragraphs
  - Remember to include key figures from the data
5. Think about how to restate the main trend(s) in the graph using different words.
  - Write the conclusion, paraphrasing the main trend(s)
6. Proofread your description.
  - Grammar: accuracy of noun phrases and verb phrases, correct verb tenses and prepositions
  - Organisation/coherence: linking words and variety of phrases/conjunctions
  - Content: is the information accurate and detailed enough? Do the details support the topic sentences?
Introduction paragraph The introduction consists of two parts:
(1) an opening sentence explaining what the graph is about
(2) one or two sentences describing the overall trend
Body paragraph 1 First main fact and supporting details relating to overall trend
Body paragraph 2 Second main fact and supporting details relating to overall trend
Concluding paragraph A brief summary of the most important information you perceive from the data

Note: the number of body paragraphs depends on the number of main ideas/major trend in the graph.

Some graphs are static, i.e. they show data at one point in time. Many graphs, however, illustrate changes in trends over several periods. Trends are tendencies, or movements in a particular direction. Describing these accurately requires specialized vocabulary. In order to write well and achieve a high mark for a graph description task, you need to use a variety of vocabulary items and not simply repeat the same nouns or verbs such as ‘increase’ or ‘decrease’.

Direction of trend Verb Noun
(going up) increased (to)
rose (to)
went up (to)
climbed (to)
an increase
a rise
a growth
a growth/an upward trend
(going down) decreased (to)
fell (to)
declined (to)
dipped (to)
dropped (to)
reduced (to)
went down (to)
a decrease
a fall
a decline

To decide which tense(s) to use for describing a graph, you need to find out whether there is a time element to the graph. Is it the past, the present or the future? Don’t forget to look at the title of the graph to see what time it relates to. If no time is given, you can presume that the data are current (see the graph in Task 1).

The general rule is:

  • if the graph deals with data in the present, or if there is no indication of time in the graph, use the simple present;
  • if the data are about the past, then use the simple past;
  • if the data are a prediction in the future, then use the simple future;
  • if there is a connection between the past and the present, then use the present perfect.
  • if there is a connection between two actions both happening in the past, with one before the other, then use the past perfect.

However, we always use the present tense for the first sentence in the introduction to define the chart/graph.
