Usage no npm install needed!

<script type="module">
  import tomgpLineSimplification from 'https://cdn.skypack.dev/@tomgp/line-simplification';


What it is?

A simplified path generator for D3, more or less a drop in replacement for d3.line with the added ability to specify a tolerance.


Install and use via npm npm install --save @tomgp/simplify-line

const { simplifiedLine } = require('simplify-line');

const simple = simplePath()
    .x(function(d){ return dateScale(d.date); })
    .y(function(d){ return valueScale(d.value); })

Based on Simplify.js a tiny high-performance JavaScript polyline simplification library by Vladimir Agafonkin, extracted from Leaflet, a JS interactive maps library by the same author.

It uses a combination of Douglas-Peucker and Radial Distance algorithms.
