About this tool

ShishwaLab Chart Generator is a free online chart maker and CSV chart generator. Paste or upload tabular data, auto-detect structure, and build interactive bar, line, pie, doughnut, area, or scatter charts in your browser.

Chart.js loads only when you generate a chart. Your data stays in the browser—ShishwaLab does not upload your dataset to ShishwaLab servers and does not call a paid AI or charting API.

Insights (maximum, minimum, percentage change, trend direction, category ranking) are deterministic calculations from your numbers—not generative AI claims.

Tips for better results

  • Prefer a header row. Use clear column names so label vs numeric detection is accurate.
  • For time series, put dates or months in the first column and metrics in the following columns—line or area is usually recommended.
  • Pie and doughnut work best with few categories and one numeric series. Scatter needs two numeric columns.
  • Very large pastes are capped for browser performance. Missing cells are skipped in numeric stats.

How to use

  1. 1 Paste CSV, TSV, JSON, or a table—or upload a .csv/.tsv/.json file.
  2. 2 Click Parse data so columns are auto-detected (labels, numbers, dates, categories).
  3. 3 Review the recommended chart type, adjust label/value columns and title, then Generate chart. Download PNG or SVG.
