A chart showing how often values fall into ranges, called bins. The bars touch because the data is continuous, making it the standard picture of a distribution.
Free AI histogram maker
Paste raw values and ask for a histogram. The bins get chosen sensibly, the bars get drawn, and the shape of your data shows itself. No frequency tables, no fighting bin settings in a spreadsheet.

What is a histogram?
A chart that shows how one continuous variable is distributed. Values are grouped into equal-width bins, and each bar's height is the count in that bin. The bars touch because the axis is a continuous scale, and the shape shows where data clusters and which values are rare.
The bars describe the sample you measured; a 95% confidence interval quantifies uncertainty around the estimated mean: across repeated samples, 95% of intervals built this way would contain the true mean. It narrows with more data, widens with more spread, and answers what the bars can't: is this shift real, or just the sample you drew?

Histogram vs bar graph: which one do you need?
They look alike and do different jobs. A bar graph compares separate categories, so the bars have gaps and any order you like. A histogram shows how one continuous variable is distributed, and the bars touch because each one is a range of values, in order. Comparing regions? Bar graph. Looking at the spread of delivery times? Histogram.
Bar graph: separate categoriesGaps between bars; reorder them freely.
Histogram: one continuous variableBars touch; the axis is ordered by value.
How to make a histogram with AI in 3 steps
1Add data, ask for the histogram
Upload a CSV or Excel file, connect a Google Sheet, or paste a single column of raw values. Then "distribution of order values" is enough: binning happens automatically, and "wider bins" or "20 bins" re-cuts them.

Order value distribution
Ask AI
Distribution of order values, mark the mean with a 95% confidence interval1,482 orders, binned at $20. The distribution is right-skewed: most orders land between $20 and $60, but a thin tail runs past $180, pulling the mean to $58 against a median of $47. The 95% confidence interval for the mean is narrow, $55–$61, so the gap is real, not sampling noise.

Histogram shapes, and what they mean
Five shapes cover most of what you'll meet, and each one tells you what to do next.
Bell-shaped and symmetric
Values pile up in the middle and taper evenly. The tidy case, where means and standard deviations behave.
Right-skewed
A long tail of large values: incomes, order sizes, response times. The mean sits above the median; a few big numbers are doing the pulling.
Left-skewed
The mirror image: a long tail of small values, like scores on an easy exam.
Bimodal
Two peaks, usually two populations mixed together. The histogram is telling you to split the data before you summarize it.
Uniform
Every bin about equally full. Common for anything bounded and random, and a red flag when you expected a peak.
Why data teams pick Deepnote as their AI histogram generator
Understands the data
Bins get chosen sensibly from your values and re-cut with a sentence ("wider bins," "20 bins," "show percentages") with no bin-width arithmetic.
Stays connected
New observations re-bin themselves. Point the histogram at a CSV, Google Sheet, or database and the shape stays honest.
Built for sharing
Publish an interactive version, embed it in the doc, or export stills for the report.
