Same numbers, different pictures
The help desk had 40 tickets this week. Fifteen were about printers, 10 about wifi, 8 about logins and 7 about other things.
Show those four numbers to an engineer, a manager and a class of students. Each needs a different picture. This lesson helps you choose it.

Six ways to show data
A graph plots values on two axes, so it shows change over time well. A chart compares amounts or parts of a whole.
A table gives exact values. A report explains findings in words with data. A dashboard shows live numbers on one screen. An infographic tells a story with pictures and a little text.
Benefits and drawbacks of each format
| Format | Benefit | Drawback |
|---|---|---|
| Graph | Shows trends over time | Hard to read exact values |
| Chart | Quick comparison of amounts | A pie chart fails with many parts |
| Table | Exact numbers | Hard to spot a pattern |
| Report | Full explanation and context | Slow to read |
| Dashboard | Live view at a glance | Can hide detail and be cluttered |
| Infographic | Easy and memorable | Little detail, and can mislead |
