Brushable scatterplot
Select and highlight specific points to filter connected data tables. Create a private, publication-ready brushable scatterplot directly in your browser without transmitting sensitive rows off-device. Data is processed locally on your hardware with zero server uploads, enabling instant export to SVG, PNG, and Excel data.
Edit the data, then export.
Everything runs in your browser. Your data is not uploaded.
Data
Paste tab-separated data from Excel or edit the cells directly.
Paste or import table data
Paste a header row, or choose a local CSV/TSV file. Files are read in this browser and capped at 500 rows.

SVG, PNG, and Excel exports are generated locally in this browser. PowerPoint export is temporarily unavailable while its dependency path is reviewed for a high-severity image parser advisory.
Visual Encoding & Comparative Anatomy
A brushable scatterplot lets you draw a rectangular selection area (a “brush”) over a group of data points to filter, highlight, or inspect them. When connected to other tables or charts, selecting points in the scatterplot automatically updates the linked components to show only the brushed data. Like all Trendalyzer tools, this chart processes all data locally on your device—no information is ever uploaded to external servers.
Input Format & Required Columns
Format input columns for brushable scatterplot with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.

Best Practices for Category Comparison
- Ensure sufficient visual distinction for brushable scatterplot marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for brushable scatterplot elements.
- Double-check scale boundaries and zero-anchors before exporting brushable scatterplot presentation artwork.
- Data shape
- Identifier, numeric x, and numeric y columns
- Exports
- SVG, PNG, and Excel data; PowerPoint export is temporarily unavailable pending dependency review.
How it works
You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.
Frequently asked questions
What is brushing and linking?
Brushing allows selecting a 2D subset of points in one chart, while linking automatically updates connected charts and data tables to reflect that selection.
