## What it is
Layer Cake is a headless visualization framework for Svelte that provides a wrapper component and layout components (SVG, HTML, Canvas, WebGL) for building reusable, layered charts. It computes scales synced to layout changes and supports both client-side and server-side rendering of responsive graphics.

## Use cases
- build custom charts in svelte
- create responsive data visualizations
- render charts server-side without javascript
- combine svg canvas and webgl layers in one chart
- make a line chart or bar chart in svelte
- build reusable chart components with shared scales

## When to choose
- you use Svelte and want full control over chart components
- you need charts that mix SVG, Canvas, HTML, or WebGL layers
- you want server-side rendered graphics that work without JavaScript
- you prefer copy-paste customizable components over a fixed chart API

## When to avoid
- you need a quick out-of-the-box chart library with prebuilt chart types
- your project does not use Svelte
- you want a framework-agnostic or React-based charting solution
