Graphs & Charts

📋 What it is

Bar charts compare categories; line graphs show change over time; pie charts show parts of a whole.

🗣️ Coach says

A chart is a picture of data — and each type answers a different question. Bars compare groups, lines track change over time, pies show slices of 100%. Choosing the wrong one hides the story or tells a false one.

🧠 Memory hook

Bars = COMPARE groups. Lines = change over TIME. Pies = PARTS of a whole. Match the chart to the question.

😲 Whoa!

The first known pie chart was made in 1801 by William Playfair, who also invented the bar chart and line graph — one person gave us three.

🤸 Brain break: Chart shapes: make a "bar" with a flat hand, a "line" zig-zag with a finger, a "pie" circle with both hands.
