In last week's lesson I gave some tips about how to write a good overview to summarise the information shown on a graph, chart or diagram. Let's look at an example overview of the graph below.

- Notice that I didn't include any specific numbers. Save the details for later.
- The first sentence describes the "big picture". The first thing I did was look at all 4 lines and the whole period. I noticed that there was an overall trend towards people having more cars (the word 'ownership' came from the question). Most students tend to miss this kind of general observation.
- The second sentence highlights the biggest changes over the whole period. With these 2 sentences, I've definitely summarised the main features of the graph.
