## What is LTTB?
Largest Triangle Three Buckets is a downsampling algorithm for time series data.
## Installation
```
npm install @seanvelasco/lttb
```
## Usage
```typescript
import LTTB from '@seanvelasco/lttb'
const threshold = 300
const untreatedData = [...]
// Accepts an array of numbers (number[]) or typed arrays (Uint8Array, Uint16Array, Uint32Array, etc)
const downsampledData = LTTB(untreatedData, threshold)
```
