(Sub) Are you throwing numbers at people, or telling them a story they can actually use?

Most charts show numbers. Few tell a story. A good visual should behave like a street sign: one glance, instant understanding.

And although this note talks about charts, the rule is wider. Whenever you share a number, you need the same core elements if you want the reader to understand it without assistance.

Here is what you need.

A value.

Highlight the number that matters. Not the whole dataset, not the decorative noise. The single point people should remember.

Some context.

Give the number a clear title. Add a short line that explains what it represents. If you use colour or shape, include a legend. Your job is to remove guesswork.

What good looks like.

Show the target or the healthy range. Without it, nobody knows whether the number is solid or slipping.

What bad looks like.

Make the danger zone visible. The point where action becomes necessary.

Why these values matter.

Give the logic. A short line on cost, risk or customer impact turns the number into a decision instead of a decoration.

To make it easier to remember, I use a small story that refuses to leave your head:

Poppy Stole Dad’s Dragon Whistle.

Poppy — Present the value
Stole — Set the context
Dad’s — Define good
Dragon — Define bad
Whistle — Why it matters

It sounds like a lost children’s book, but that’s exactly why it works.
Once you remember Poppy and the dragon whistle, you remember the structure.

PSDDW: Present, Set, Define good, Define bad, Why.

When all five are present, your numbers speak for themselves.

A brief note for paid members:
I’m putting together a small Graph Clarity Toolkit that goes further. It includes quick rules for choosing the right chart, spotting when visuals quietly hide part of the story, and avoiding the common traps that distort reality. It will be released soon as a compact, practical PDF.
