The Ideal Structure
Introduction (1–2 sentences): Paraphrase the question. State what the visual shows, the time period, and units of measurement. Never copy the question word for word.
Overview (2–3 sentences): Identify the two or three most significant features — the overall trends, the largest/smallest values, or the most notable changes. This paragraph is essential. According to the IELTS band descriptors, a response without a clear overview cannot achieve above Band 5 for Task Achievement.
Body Paragraph 1 (3–4 sentences): Describe one group of related data with specific figures.
Body Paragraph 2 (3–4 sentences): Describe the second group of related data, making comparisons where relevant.
How to Describe Data Accurately
Describing trends
Use a combination of verb + adverb or adjective + noun to describe changes:
| Change | Verb + Adverb | Adjective + Noun |
|---|---|---|
| Big increase | rose sharply, surged dramatically | a sharp rise, a dramatic surge |
| Small increase | increased slightly, grew marginally | a slight increase, a marginal rise |
| Big decrease | fell dramatically, plummeted sharply | a dramatic fall, a sharp decline |
| No change | remained stable, stayed constant | a period of stability |
| Up and down | fluctuated between X and Y | a period of fluctuation |
Process Diagrams and Maps
Process diagrams and maps require a different approach from data charts. Use the passive voice extensively for processes (“The raw materials are transported to the factory”) and location language for maps (“To the east of the main road, a new residential area was constructed”).
