A Visualization Is Based on Selected Data
A chart does not show “the whole truth about the dataset.”
It shows the fields, filters, groups, and calculations chosen for that visualization.
For example:
- New
- Changed
- Removed
Every stage matters.
A large table contains detail.
A visualization can make selected patterns easier to see.
Charts are especially useful for noticing:
The chart is not creating those patterns.
It is changing how the data is represented.
Suppose a table shows:
| Genre | Song Count |
|---|---|
| Jazz | 12 |
| Pop | 19 |
| Rock | 28 |
The table makes exact values easy to read.
A bar chart of the same values makes the relative difference between the categories easier to see quickly.
Use the representation that supports the question.
A chart does not show “the whole truth about the dataset.”
It shows the fields, filters, groups, and calculations chosen for that visualization.
For example:
Every stage matters.
When viewing or creating a chart, ask:
Then ask:
That combination turns a chart from decoration into evidence.
