Vector field generator

Vector field

Plot direction and magnitude at sampled positions to reveal movement, force, or flow patterns. Create a private, publication-ready vector field 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.

Multi-Variable Correlation & Flow Mechanics

A vector field chart (often called a quiver plot) maps the direction and magnitude of forces or movement across a 2D space. By drawing arrows (vectors) at discrete coordinates, the angle shows the directional heading while the arrow length or color indicates velocity, force, or intensity. This tool processes your data completely locally—no information is ever uploaded to a server, guaranteeing complete privacy for your datasets.

Coordinate & Matrix Data Structure

Format input columns for vector field with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.

Correlation Traps & Analytical Guidelines

Ensure sufficient visual distinction for vector field marks across standard and high-contrast viewports.
Align text labels horizontally whenever possible to improve cognitive readability for vector field elements.
Double-check scale boundaries and zero-anchors before exporting vector field presentation artwork.

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 does the length and angle of each arrow represent?

The angle represents directional heading (e.g. wind bearing), while arrow length and color represent magnitude (e.g. wind speed).
