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

说明与用途

Honest Chart 是一个网页，展示从 CSV 文件生成的图表，并显示文件的 SHA‑256 哈希值，帮助验证数据未被篡改。

问题

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

结果

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.

工作流

• 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.

证据

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