Chart Builder

Chart Builder turns tabular data into a downloadable chart entirely in your browser, using the ApexCharts rendering engine.

1. Paste your data as CSV or a copied spreadsheet range. The delimiter is auto-detected (comma, tab, semicolon or pipe), or pick it manually.
2. Describe the layout with the two checkboxes; whether the first row is a header and whether the first column holds category labels.
3. Pick a chart type; bar, line, area, pie or scatter.
4. Customize the title, axis labels, legend, grid, data labels and per-series colors.
5. Export the finished chart as a raster PNG or a crisp, scalable SVG.

Data format

• Bar / line / area: first column = category labels; each remaining column = one series. Multiple numeric columns become grouped/overlaid series.
• Pie: first column = slice labels; the first numeric column = slice values (extra columns are ignored).
• Scatter: supply two numeric columns as x, y pairs. A header row can name the axes.

Notes

• All processing is client-side; your data never leaves your device.
• SVG exports are vector graphics; ideal for print, slides and further editing.
• Charts follow the site's light/dark theme automatically.

You can embed this util on your own site as a widget. Adding ?embed=1 to the URL loads a compact version with just the tool itself; no header, menu, or documentation. Paste this snippet into your HTML:
