How the One‑Sentence Chart Generator Works

Our natural language chart generator analyzes your sentence to extract time periods (monthly, quarterly, weekly), metrics (sales, revenue, traffic), and optional years. It then generates a realistic or custom dataset that matches your description. For precise control, paste your own CSV data (e.g., from Excel or Google Sheets) — the chart updates instantly. All processing happens inside your browser: no data leaves your device, ensuring privacy and speed.

Supported natural language patterns: “last year monthly sales”, “quarterly profit 2023”, “weekly website visits Jan–Mar”, “daily temperature in July”. For advanced users, CSV mode supports any labels and numeric values.

CSV Format Guide & Chart Engine

  • CSV format: First row as headers (e.g., Category, Value). Subsequent rows: label, number. Example: Jan,1200 or Q1,4500.
  • Natural language parsing: Uses keyword mapping (monthly → 12 months, quarterly → 4 quarters, last year → previous year labels). Generates sample data with realistic trend (upward/downward based on context).
  • Chart.js engine: Supports bar/line toggle, responsive scaling, and vibrant gradients. Click the bar/line buttons to switch chart type without re‑generating data.
  • Privacy: No server upload; your data never leaves this page.

Perfect for quick data exploration, presentation mockups, educators, and business analysts who want instant visualization without spreadsheet software.

Frequently Asked Questions

❓ Can I use my own data from Excel?

Yes. Copy two columns (e.g., Month and Sales) from Excel, paste into the CSV textarea, and click “Apply CSV”. Make sure values are numeric.

❓ How accurate is the natural language chart?

It generates a plausible dataset based on your description. For actual numbers, use CSV mode. The tool is meant for quick visualization, prototyping, and learning.

❓ Can I export the chart as image?

Not yet built into this version, but you can right-click the chart → “Save image as” (PNG) on most browsers. Full export coming soon.

❓ Does it support other languages (e.g., Spanish, French)?

Basic English only for now, but CSV mode works with any language labels. We plan to expand NLP to more languages soon.
