Definition
Chart
A chart is an organised visual display that makes data or mathematical information easier to read.
What it means
A chart turns information into a pattern you can scan. First identify what each label, bar, point, slice, line, or symbol represents. Then read the scale or key before comparing values, because different chart types use different visual rules.
Remember it
Read the title, labels, scale, and key before the picture.
Example
A bar chart shows books read: Amina 4, Ben 7, and Chen 5. Ben’s bar reaches 7, so Ben read the most. The difference between Ben and Amina is 7 − 4 = 3 books.
Watch for
Chart is a broad label. A specific chart type has its own structure, scale, and reading rules.
Common mix-up
A chart is not automatically a graph of a mathematical function; charts can include bar charts, pie charts, pictograms, and other organised displays.
Exact meaning
A chart is a structured visual display of data or mathematical information. Its type—such as a bar chart, pie chart, or line chart—determines how values, categories, or changes are encoded and how the display should be read.
