Answer:
Charts are the graphic representation of data.
Step-by-step explanation:
There are several types of chart and data can be represented in different ways, such as bars (the chart is called bars chart,) lines (line chart) or slices (as in a pie chart.) They are used to make people understand data in an easier way because they are friendlier than raw information, even though there are large amounts of data contained in them.
Another important fact is the title of the chart, since it summarizes its main intention. If the chart contains multiple variables, it is necessary to indicate them with a legend or key. The chart also contains axes, usually x and y. using these elements, much information can be inferred, such as the trends and how they change through time.
