The easiest way to add data is to copy cells from Excel or Google Sheets and paste them into the data input field — our parsers handle tab-separated values from spreadsheet pastes automatically. You can also type comma-separated values directly. For structured datasets, some tools accept CSV-formatted text. Manual row-by-row entry is available for small datasets where you want precise control over labels and values.

Charts generated in your browser are interactive by default — hover over any slice, bar, or data point to see a tooltip with the exact label and value. Pie charts highlight the hovered segment. Bar and line charts show crosshair guides on hover. When you export to PNG, the chart is rendered as a static image capturing the default state at the resolution you select. Interactive features are available while you customize and preview the chart before export.
