chart your data and export it, without leaving the page

Drop a file or paste a table, switch the canvas to chart, and draw it. Bar, line, area or point, with an aggregate when you want one - and the picture is a view of the same pipeline everything else here runs on, so filtering by dragging leaves a step behind rather than a hidden selection.

how to use it

Drop a file anywhere on the page, or paste a table straight from Excel, Sheets, or a SQL client. Nothing uploads - there is nowhere to upload it to.
Switch the canvas from grid to chart, then pick a mark, a column for x, and what the values are - a count of rows, or a sum or average of another column.
Drag across the chart to narrow it. That writes a real keep rows step into the pipeline, so the range survives export, a saved recipe, and a share link.
Export the picture as svg or png, or copy the Vega-Lite spec that drew it - the same spec renders in the Vega editor, Observable, Altair or R.

what it does

Four marks, honestly labelled: bar, line, area and point, coloured by any column, following whichever theme you have on.
It tells you what it summed: the canvas holds the first 1,000 rows, so an aggregate over a bigger file says so and offers to recompute over every row in the engine rather than quietly charting a sample.
Pivot underneath: the engine's pivot step spreads one column's values across the top, so a wide table and a chart of it are two clicks apart - and it generates the SQL.
The spec is the export: what you copy is what drew the picture, not a reconstruction of it.
Zero server, 100% in your browser: the chart engine loads on demand and your rows never leave the tab.

Like every unfckr tool, this runs 100% in your browser: no upload, no servers, no signup, no analytics. A Content-Security-Policy header blocks every programmatic network channel, so not even malicious code could phone home - and you can watch it happen: the privacy page runs six live escape attempts and shows the browser refusing each one.
