I built a CSV chart page that shows a SHA of your file so the chart can’t invent numbers

Описание и применение

Honest Chart – веб‑страница, которая отображает график из CSV‑файла и SHA‑256‑хеш файла, позволяя проверить, что данные не изменены.

Задача

Charts can display correct-looking visuals while using incorrect or altered data, undermining trust in quick visualizations.

Результат

The tool provides an immediate visual cue that the chart is based on the exact uploaded data, reducing the risk of data tampering in quick visualizations.

Рабочий процесс

• Upload a CSV file via the web interface.
• The page renders the chart based on the CSV data.
• A SHA‑256 hash of the CSV file is calculated and shown beside the chart.
• Viewers can copy the hash and compare it with the original file’s hash to verify integrity.

Доказательства

I built Honest Chart, a free CSV→chart page that shows a SHA‑256 fingerprint for the uploaded file alongside the chart.
