Free AI bar graph maker

A chart that shows categorical data as rectangular bars, each bar's length proportional to its value. The quickest way to compare quantities across categories.

Nothing — the terms are interchangeable. "Bar graph" is more common in schools, "bar chart" in business. Deepnote treats them as one chart family.

A bar graph compares separate categories, so the bars have gaps. A histogram shows the distribution of continuous data in bins, so the bars touch.

Bars compare amounts across categories, lines show trends over time, pies show parts of a whole. When in doubt, bars are the most readable choice.

Paste or upload your data in Deepnote, describe the chart you want, and download it as PNG, SVG, or PDF. No credit card, no watermark.

Yes — Deepnote runs in your browser. If your data lives in Excel or Google Sheets, upload the file or connect the sheet and the chart builds itself.

A bar graph with two series side by side per category — like test scores for two classes. Add a second value column and Deepnote groups them automatically.

Each bar splits into segments, showing the total and its composition. Use the 100% stacked version when proportions matter more than totals.

Vertical suits time-based categories. Go horizontal when labels run long or you're ranking many items — everything stays readable.

Descriptive title, both axes labeled with categories and units, and a value axis that starts at zero so bar lengths don't mislead. Deepnote's AI can do it for you.

Yes. Export PNG, SVG, or PDF for slides, or use an embed code or share link for the web. Shared charts stay connected to the data and update automatically.
