Title, axes, scale, legend, then the question.
A runs-per-over graph tells the story of a T20 match.
Missed a cricket match? A graph like this tells the story in a minute.
Answering the book's four questions from the graph.
Problem. Answer the book's four questions from the graph. (Textbook p. 122)
Questions on the animal-speed infographic.
The book's infographic (p. 123) shows top speeds in km/h. Air: peregrine falcon 322, spine-tailed swift 170, free-tailed bat 96, green darner dragonfly 64, flying fish 56.

Can we call this graph a bar graph? (Textbook p. 122, Q1)
The graph for the next task.
Figure it Out, Textbook pp. 124–125, Q4. Electric vehicles registered per year in some states (bars read approximately from the book):
Read, complete and question a clustered bar graph.
Figure it Out, Textbook pp. 124–125, Q4. Use the electric vehicle graph shown above.
(a) The data for Gujarat and Delhi, rounded to thousands, is:
| | 2022 | 2023 | 2024 | |---|---|---|---| | Gujarat | 69000 | 89000 | 78000 | | Delhi | 62000 | 74000 | 81000 |
Where would these bars reach? Then answer (b)–(f).
Gridlines every 25000.
Organisation, scale, patterns.
Read the bars approximately.
What does each bar show?
