Histogram Chart Maker
How to use the Histogram Chart Maker
- Open the Histogram Chart Maker and review the sample Value column.
- Paste your own numeric CSV — one Value column is enough.
- Bins and frequencies update live as you edit values.
- Switch themes and download a high-res PNG.
Why chart locally?
Distribution analysis often uses sensitive measurements. Histograms bin and render entirely in your browser.
Frequently asked questions
What CSV format does the histogram need?
A header row plus a numeric Value column (Amount, Count, or Data also work). At least two numbers are required.
How are bins chosen?
Bin count follows Sturges’ rule (clamped between 5 and 20). Equal-width bins cover the min–max range.
Is my data uploaded?
No. Parsing and rendering are 100% client-side.
