Using Charts for Data Representation

Charts are a way of representing data visually, making it easier to understand and compare.
Instead of reading long lists of numbers in a table, charts use shapes like bars, lines and slices to
tell the "story" of the data instantly.

Charts plot data on coordinate axes, where the X-axis represents categories and the Y-axis
shows values. By turning data into a visual format, charts help us see patterns and trends
quickly.

A chart has different parts that work together to display data clearly. The main components of
charts are as follows:
 Chart Area: This is the whole space that holds the chart, including everything like the title,
axes and data.

 Chart Title: The title tells you what the chart is about, so you know what data it is showing.

 X-axis: The horizontal line (left to right) that shows the categories or groups of data.
 Y-axis: The vertical line (up and down) that shows the values or measurements of the data.

 Plot Area: The space where the data is shown, excluding labels and the title.

 Data Series: The actual data points shown on the chart. These are represented by bars, lines
or dots.
 Data Labels: The numbers shown next to the data points to tell you the exact value.

 Gridlines: The horizontal and vertical lines that help you read the values easily by dividing the
chart into sections.

 Legend: The part that shows what each colour or symbol means in the chart.
