Data can be represented in different ways – in a table or in a graphical form. When organised into a graph, one gets a quick visual representation of the data. There are different types of graphs that help us find patterns and trends in data.
Graphs are used in many aspects of our day to day lives, such as business presentations, newspaper articles, utility bills, loans/investments by banks, and so on.
Let us look at the common features of a graph. Every graph must have –
- a title
- the axes should be clearly labelled
- the values/divisions shown on each axis must be consistent and equally spaced
- scales on each axis must be clearly stated
- if required, a key explaining some aspects of the graph should be provided
