Histogram Maker

Averages alone rarely tell the whole story. In spreadsheets, logs, surveys, and QA measurements, you often need to understand how values are distributed across ranges before deciding what they mean. A histogram helps you see where values cluster, whether the distribution has one peak or several, and whether outlier candidates deserve a closer look.

This histogram maker takes comma-separated or line-separated numeric values, groups them into bins, and draws an SVG histogram. You can adjust the bin count to compare different levels of detail, then review the mean, median, standard deviation, minimum, maximum, and count alongside the chart. It is useful for lightweight analysis, report drafts, teaching materials, QA notes, and quick checks before moving data into a spreadsheet or statistics package.
