# How to Create Comparison Charts with ChatGPT

ChatGPT approaches chart creation as visual storytelling, helping you think through not just what data to show but how to present it for maximum impact. Describe your data and who will see the chart, and get a professional visualization along with suggestions for chart type, color scheme, and layout. ChatGPT excels at recommending the most effective presentation format for different contexts -- whether you need a clean executive summary chart, a detailed comparison, or a compelling visual for a blog post.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT settings
2. Ask: "Create a comparison chart showing this year versus last year performance"
3. ChatGPT generates a clear comparison visualization
4. Request: "Highlight the areas where we improved most"

## Example Prompt

```
Generate a comparison bar chart showing Q1 2025 vs Q1 2026 metrics: Revenue ($2.1M vs $3.2M), Users (45K vs 78K), NPS (42 vs 61), Churn (5.2% vs 3.1%).
```

## Tips

- ChatGPT can recommend which comparison format best highlights your key message
- Ask for annotations that call attention to the most significant differences
