What columns does my grades CSV need?
A name or identifier column and a score column. For distributions, a single score column is enough — the histogram bins it for you.
Histogram for Grades
Scores, results and rankings — grade data is small, human and instantly recognizable in a chart, which makes it ideal for reports and classroom summaries.
Example: grades as a histogram

Download the histogram as PNG, SVG or CSV, or open it in Studio to tune colors, labels and sorting.
Why a histogram fits grades
A histogram is built for distribution: values are binned so you can see where the mass sits, how wide the spread is, and which way the data leans. For grades, a column of numbers turns into a shape you can argue with.
