Upload CSV, Excel, or PDF, map columns to chart roles, overlay reference ranges, filter by date or value, and export publication-ready charts. Everything runs in your browser.
Powerful features designed to make data visualization simple, fast, and beautiful.
Upload .csv, .xlsx, .xls, or .pdf files. Multi-sheet workbooks and text-based PDFs are supported — scanned PDFs use OCR as a fallback.
Assign roles to each column: X-Axis, Value Series, Reference Lower/Upper, Label, or Ignore. Smart defaults applied automatically.
Shade the normal range band behind your data lines. Ideal for lab values, sensor limits, or quality thresholds.
Filter by date range, value range, or category. Attach unit labels (ng/dL, mIU/L) to axes and tooltips.
Download publication-ready charts. No watermarks, no account required, no data sent to any server.
Everything runs in your browser. Your data never leaves your device — no backend, no AI, no tracking.
