## What it is
Svelvet is a lightweight Svelte component library for building interactive, node-based user interfaces and flowcharts. It provides customizable nodes, edges, zooming, panning, and snap-to-grid features for creating dynamic diagram UIs.

## Use cases
- build interactive flowcharts in svelte
- create node-based editors with drag and drop
- visualize workflow diagrams on a canvas
- build node graph UIs with connecting edges
- make a data pipeline diagram editor
- add zoomable panable diagram canvas to a sveltekit app

## When to choose
- you are building with Svelte or SvelteKit and need node-based diagram UIs
- you want a lightweight React Flow alternative for the Svelte ecosystem
- you need customizable nodes, edges, zoom, pan, and snap-to-grid out of the box

## When to avoid
- your project uses React, Vue, or another framework rather than Svelte
- you need static diagram rendering rather than interactive node editing
- you require a long-term support guarantee, since the repo has no declared license file
