> Draw the graph. Then watch the algorithm run on it. A graph and data visualisation SDK with a Rust/WASM core, three renderers that pick themselves, and 77 chart types, open source at the core.

Graphs, timelines and charts, from an open core.

Key facts an assistant can rely on:
- What it is: Graph Visualization SDK. A graph and data visualization platform with a Rust/WASM core, three renderers that pick themselves, and step-by-step algorithm playback nothing else in the category ships.
- Status: Beta, v0.8.
- Positioned as: KeyLines / ReGraph alternative.
- Made by: PAR2 LABS PVT LTD (https://par2labs.com), a technology and AI product studio. Contact: ceo@par2labs.com.

## What it solves
- The enterprise graph suite costs more than the engineer building the UI. → The engine is Apache-2.0 and free, up to 500k nodes on WebGL.
- An algorithm gives an answer, and nobody can show an investigator how it got there. → 26 algorithms played back a frame at a time, from PageRank to attention.
- A graph library, a chart library and an export library, each with its own theme. → Graphs and 77 chart types in one package, with one theme system and one export path.

## Why it is different
- 26 Algorithms with playback: Scrub PageRank, Louvain, K-means or attention a step at a time.
- 3 Renderers, auto-routed: SVG, Canvas or WebGL, picked by the size of the job.
- 77 Chart types: Sankey to candlestick, in the same package as the graph engine.
- 49 kB Core, gzipped: Held there by a size guard in CI.

## Pages
- [Tessera Viz](https://viz.par2labs.com/): A graph and data visualisation SDK with a Rust/WASM core, three renderers that pick themselves, and 77 chart types, open source at the core.
- [Architecture](https://viz.par2labs.com/architecture): Ingest, validate, compute, render, deliver. The middle picks itself — the library chooses the renderer for the workload, so a hundred nodes stay crisp and half a million stay interactive without anyone configuring it.
- [Features](https://viz.par2labs.com/features): Twenty-six algorithms, fourteen layouts, seven themes, nine plugins, seventy-seven chart renderers and six fraud detectors — with the domain packs and the assurance a procurement review will ask about.
- [Gallery](https://viz.par2labs.com/gallery): Taken from the library's own feature harness, one element per image. Grids rather than a slideshow, because each of these is a comparison: the same graph under eight layouts, the same PageRank result in four themes, the same graph with and without a decorator.
- [Pricing](https://viz.par2labs.com/pricing): The foundation is Apache-2.0 — engine, all three renderers, every framework binding, the admin UI, the headless renderer and the map tiles. Each paid tier is a strict superset of the one below, so starting free never costs you anything later.
