Prompt

Act as a data visualization and presentation storytelling specialist for business decks. Your goal is for the audience to get the takeaway in five seconds.

Context:
- Data (pasted table, with units and period): {{data}}
- Audience: {{audience}}
- Decision or message this slide must support: {{decision}}
- Tool: {{tool}}

Deliverables:
1. Data read-out: the 2-3 most relevant observations, with any calculations you did (changes, percentages, averages) shown step by step.
2. Action title: a full sentence stating what to understand (not "2024 Sales" but the takeaway), plus two alternatives.
3. Recommended chart type and why, and which charts to avoid with this data.
4. Slide design: which series to highlight in color, what to mute in gray, what to remove (legends, gridlines, decimals, 3D) and where to label data directly.
5. Annotations: one or two short callouts on the chart explaining the key point (for example, what caused a spike).
6. Step-by-step instructions to build it in {{tool}}.
7. About 60 seconds of speaker notes using a context, tension, resolution structure and ending with the decision I am asking for.
8. A backup slide in case the audience is skeptical: which supporting data to show.
9. Data caveats: sample size, period, definition changes or anything else that could lead to a wrong conclusion.

Constraints:
- Use only the data I give you. Do not invent figures, market benchmarks or causes; if an explanation needs information that is not in the table, mark it [FILL IN: confirm cause].
- Double-check every calculation and do not round in a way that changes the conclusion.
- If the data does not support the decision I want to argue for, tell me plainly.
- If information is missing (units, period, source), ask me first.

Format: numbered sections, calculations in a table, a slide sketch described by zones (title, chart, annotations, source footer) and speaker notes at the end.

How to use it

Paste the table with headers, units and period. Check the calculations before you use them and add the real data source to the slide footer. If it tells you the data does not support your decision, better to know before the meeting.

Usage example

Data: monthly sales by channel (store, website, marketplace), January to December in USD · Audience: leadership · Decision: increase the website budget · Tool: PowerPoint.

Sample output

You haven't pasted the table yet, so figures are left as [FILL IN]. Once I have the real data, I'll also check whether it supports asking for +20% for the website.

Data read-out (structure)

  1. Website growth: (Dec website sales − Jan website sales) / Jan website sales = [FILL IN]%
  2. Website share of total: annual website sales / total sales = [FILL IN]%
  3. Comparison with other channels over the same period: [FILL IN]

Action title

"The website already brings in [FILL IN]% of sales and is growing faster than any other channel: we propose a 20% budget increase" Alternatives: "The website is the only channel that grew every quarter" (only if the data confirms it) · "Each extra dollar on the website [FILL IN: only if return data exists]."

Monthly line chart, website in color and other channels in gray. Avoid: pie charts (no trend), 3D bars, twelve different colors.

Design

  • Label each line directly at its end; no legend.
  • No decimals or gridlines.
  • One callout: [FILL IN: confirm cause of the November spike, if there is one].

Speaker notes (60 s)

Context: this year we sold [FILL IN] across all channels. Tension: …

Frequently asked questions

What is an action title?

A title that states what the audience should understand, such as "The website now drives 40% of sales", instead of a generic topic like "Sales by channel". Someone reading only the titles should still get the story.

Why highlight only one series?

If everything is in color, nothing stands out. Coloring only the series that matters and graying out the rest guides the eye to the conclusion.

What if the data does not support my proposal?

The prompt is designed to tell you. It is better to adjust the proposal or gather more data than to present a slide someone can take apart in the meeting.

What is this prompt for?

Turn your data into one clear slide: an action title, the right chart, what to highlight and what to remove, annotations, 60-second speaker notes and caveats about the data.
