Look at your data.[1–12]
All hundred million rows of it.
Easy advice at a thousand rows, hard at a hundred million. QPlot draws every row and keeps pan, zoom and recolor at full frame rate. Try a dataset on the right, or drop yours.
Your file stays on your machine. No account needed.
payment_type
Real rows from the demo file. This preview draws a 12,000-row sample on a 2D canvas; QPlot draws all of them on the GPU.
Datasets that show what full resolution feels like
Each opens as a live document. Pan, zoom, recolor, facet, hover a point. Nothing is sampled.
What QPlot does with a file
Read only what the plot needs, describe the plot with a grammar instead of a chart menu, and compute the statistics on the GPU so they keep up with the view.
Reads only the columns you plot
Parquet, Arrow and CSV are read column by column, in ranges, from disk or a URL. Columns you never bind are never loaded, so a 100M-row file opens in seconds.
A grammar, not a chart menu
Bind columns to x, y, color, size and facet; choose points, lines, density or images as the layer. Swap one binding and the same rows re-plot, as the preview above does.
Statistics that keep up
Histograms, 2D density, smoothing and correlation are computed on the GPU for whatever is in view, and recomputed as you pan and zoom.
Derived columns and filters
Add an expression, bin a value, reorder a categorical, or filter one plot without touching the others. The results are columns like any other.
Share live plots, not screenshots
Save views as slides, build a deck, share a link. Teammates open the live document and keep exploring. The data stays where it already lives.
Your GPU, your machine
WebGPU in the browser or the desktop app on Metal. Local files never leave the device; URL sources stream straight to the GPU. There is no upload step.
[1–12] The headline is a quotation. Wilkinson & the APA Task Force, 1999: “before you compute any statistics, look at your data.” Eleven more say the same thing, 1925 to 2019.
This is taking longer than usual — the app is about 5 MB. It will open as soon as it arrives.
