Data chart studio
Turn CSV or pasted tables into grouped bars, lines and pie charts. Edit data, choose series and aggregation, review plotted values, and export PNG, SVG or a printable report locally.
From a table to a chart you can explain.
Paste or import a table
Imports replace the current table; Undo restores it. First row is the header.

How to use
- Paste a table, import CSV, or edit the example.
- Choose categories, series, chart type and explicit missing/grouping rules.
- Generate, review the chart and plotted table, then download images or save the project.
Before you start
CSV/TSV with a header, UTF-8, up to 1 MB, 1000 rows and 20 columns. Edit 20 rows per page; cells up to 300 characters. Select one category column and up to three numeric series. Choose decimal dot or comma; no thousands separators, currency symbols, percent signs or formulas. Numbers up to ±1 trillion with six decimal places. Blank numeric cells default to missing, not zero; an explicit zero option is available. Entirely blank rows are omitted and counted; malformed numbers and empty categories stop generation with a row reference. Repeated categories can remain separate, sum, or average nonmissing values; grouping trims labels and is case-sensitive. Sort by source order, label or first series. Up to 60 bar categories, 30 line points or 12 pie slices; never silently truncated. Pie charts require one series, nonnegative values and a positive total. Line positions are equally spaced categories, not parsed dates or a continuous numeric axis; missing values break lines. Example: Library visits 12 and 18 in two rows sum to 30 or average to 15. Bar axes include zero. Line point labels show only at 12 or fewer points; the full data table remains available. SVG labels may shorten long text; reports retain full plotted data. PNG is rendered locally at 1×/2×; no external fonts. JSON saves the editable project up to 2 MB, with no autosave. No XLSX import, statistical inference, live data, uploads or public chart hosting.
