lttb is a TypeScript implementation of the Largest Triangle Three Buckets (LTTB) downsampling algorithm. It reduces the number of data points while preserving the visual shape of the data, making it ideal for time-series visualization or large dataset processing.

$3

- Efficiently downsamples large datasets.
- Preserves the visual characteristics of the original data.
- Written in TypeScript for type safety and better development experience.
- Easy to integrate into existing projects.

`bash
import lttb from 'js-lttb';

const originalData = [
[0, 1],
[1, 5],
[2, 3],
// ... more data points
];

const downsampledData = lttb(originalData, 100); // Downsample to 100 points
console.log(downsampledData);
