Datavisly is a free suite of studio-class applications for researchers and engineers — plot publication-quality scientific graphs, process bathymetry & terrain grids, and map GeoJSON, KML & Shapefiles. Everything runs on your device; your data never leaves it.
Works with the formats you already use
Applications
Each application is a full working environment, not a widget — open a file and get real work done without installing anything.
Scientific graphing studio
Import a CSV and build publication-quality figures on a print page. Every axis, curve, label and legend is an editable object — arrange the page exactly how the journal wants it, then export clean vector output.
Bathymetry & terrain grid studio
A grid workbench for tsunami and coastal modelling workflows. Convert GEBCO Esri ASCII to Surfer 6 grids, run grid math, resample and contour — streaming multi-gigabyte files entirely in your browser.
Interactive map studio
Drop in GeoJSON, KML, GPX or zipped Shapefiles and see them on an interactive map. Overlay and restyle layers, dig into attributes in a sortable table, then convert between formats on the way out.
Why Datavisly
Every file is parsed and processed locally in your browser. There is no server, no upload and no account — private by architecture, not by policy.
No account, no email, no trial clock. Open a link and start working — the full feature set is free.
Vector-accurate rendering and numerically careful processing, designed for scientific and engineering work — not marketing dashboards.
CSV, GeoJSON, KML, GPX, Shapefile, GEBCO .asc, Surfer .grd, SVG, PNG — standard files in, clean standard files out. No lock-in.
Quick tools
Open any CSV file and view it as a clean, sortable table. Parsed in your browser — nothing is uploaded.
Explore and format JSON with a collapsible tree view. In your browser, always private.
Turn a table into a shareable chart in a few clicks — no code, no upload.
Open an app and start working — free, private, and ready in the time it takes the page to load.
