Chart Maker
Free online chart maker tool, bar/line/pie charts supported
Creating Charts from Data
Enter your data in CSV format (Label, Value) — one row per data point. Choose a chart type (bar, line, pie, or doughnut). Customize the title, legend, and grid options. The chart renders in real time and can be downloaded as PNG.
When to Use Each Chart Type
Bar charts compare values across categories. Line charts show trends over time. Pie charts show proportions of a whole. Doughnut charts are similar to pie but with a hollow center for a cleaner look.
▶What data format does the chart maker accept?
Enter data as CSV with two columns: Label and Value. For example: January, 100\nFebruary, 150\nMarch, 200. Each row is a data point.
▶Can I download the chart?
Yes, click the Download PNG button to save the chart as a PNG image file. The downloaded image uses the current chart size and styling.
▶How many data points can I include?
The tool handles up to several dozen data points comfortably. For very large datasets, consider using a dedicated data visualization library.
