Describing charts and graphs. Different types of charts, graphs and diagrams

In this unit, we will learn about line, bar and pie-chart (circle graph). We will learn how to read and interpret information from each type of graph, and how to construct these graphs. In this unit we will look at the language used to describe charts and graphs. Graphs or charts are used to present information and data.You can use them to make a comparison or show a trend. The information below will help you determine which type of graph to use.
