Heatmap Calendar for Daily Patterns AI Prompt

Heatmap Calendar for Daily Patterns is a intermediate prompt for visualization. This prompt helps the AI turn raw data into charts or dashboards that communicate insight clearly. It goes beyond simply plotting values by asking for chart choice, layout, annotations, and business interpretation. Use it when you need visuals that are ready for exploration, reporting, or stakeholder communication. It is best suited for direct execution against a real dataset. The requested output can include more technical detail, prioritization, and interpretation while still staying practical.

Prompt text
Create a calendar heatmap to reveal daily and weekly patterns in this time series:

1. Aggregate the primary metric by day
2. Create a GitHub-style calendar heatmap where:
   - Rows are days of the week (Mon–Sun)
   - Columns are weeks
   - Cell color intensity represents the metric value (lighter = lower, darker = higher)
3. Use a sequential color palette (e.g. light yellow to dark green)
4. Add month labels along the top
5. Add a color bar legend showing the value scale
6. Annotate the 3 highest and 3 lowest days with their exact values

Below the chart, answer: Is there a clear day-of-week pattern? Is there a clear seasonal pattern across months?

When to use this prompt

Use case 01

When you need a chart or dashboard that highlights the key message clearly.

Use case 02

When a table alone is not enough for stakeholders to understand the result.

Use case 03

When you want a presentation-ready visual with labels, annotations, and styling guidance.

Use case 04

When comparing segments, trends, correlations, or composition visually.

What the AI should return

The AI should return the recommended chart specification, plotting code when appropriate, and a short interpretation of what the visual is meant to show. Titles, labels, annotations, and layout choices should be explicit so the output is presentation-ready rather than generic. If multiple charts are requested, they should be organized in a logical order and tied back to a single story. The final answer should make it clear what the viewer should notice first.
